How Not To Set Yourself Up For Failure Working A H
When I started working from home, I was elated, nervous, unsure, Gucci silk srarf, and overwhelmed at the same time. I have wanted to work from home for quite a while. Before starting, there were the endless hours of Internet searches, message boards, and search engines, trying to find the right work from home opportunity. It got frustrating because there is so much out there! When I finally found my opportunity, I told myself, I will persevere, I will not quit, I will work hard, and I will go as long as it takes for me to succeed.
I know many of you have been in my shoes - running to a supply store, and stocking up on paper, pens, Nike shox OZ, copier paper, printer cartridges, staplers, and white-out. You go online and order your business cards and flyers. You keep all of the receipts so you can deduct them next tax season. You might have even upgraded your computer software, bought a new fax/copier/printer/scanner, and unlimited long distance on your phone.
Then you're sitting in front of the computer in your makeshift office, and you log on, check your email, and get started marketing your business. You're adrenaline is running on high, and you know that everyone on the web can't wait to see what you have to offer. You just can't wait to get your products, and ads out there and start making sales, and attracting prospects. After you work hard all day, Nike Shox TL3, you complete your first day of business, check your email once more and log off, proud of a job well done.
The next morning, you awaken - barely slept a wink because you're excited and just know you've got work to do. You go into your office, turn on your computer, check your email, and check your web site stats. You're almost shocked into reality when you see that nothing happened, and that you didn't become rich overnight.
What happened? Why didn't anyone just flock to your web site and buy your products? You worked hard all day! And that's the first thing you need to understand to succeed:
ü Give yourself a daily reality check - Know that it's going to take some time, consistency, passion, motivation, and patience before you start to see results. That's what having your own business is all about. You must possess all of those things if you have a shot at success.
ü Get over your fear of rejection - You WILL hear more 'no's than you hear 'yes'. That's just the facts of life...Keep in mind you can never say the wrong thing to the right person, or the right thing to the wrong person. Shake it off and move on. (But when you're not the 'little guy' anymore, those people will kick themselves, their loss).
ü Be able to be coached - If you are involved and active, and even if you're not, you will learn something EVERY SINGLE DAY. Take everything you learn to heart, continue to improve, and if you are with a reputable business, don't try to reinvent the wheel, they are successful for a reason. Learn from your mistakes, and let people help you.
ü Be adaptable - Okay, Women's A&F HCO Jacket Long, this is kind of old school, but it's so true. It's especially true if you are doing business online. Things change by the millisecond everyday, and you have to be able to keep learning, change what doesn't work, and continue to stay informed of anything that may affect your business.
ü Don't go into a deep funk - There will be good days and bad days, we all know that. We don't like to talk about the bad days, but it's not the end of your business if you are not making sales or profit every day of the week. It goes back to being consistent. Stay on top of it.
ü Get to know your product - You can't find value in what you are selling if you've never tried it yourself. It's kind of like talking to people about McDonalds, Nike Air force 1 high for women, but you've never eaten there. Why? Don't do it. You are more passionate, and more natural when talking with prospects when you know what you're talking about, and people will see through that.
I'm positive there is plenty more advice to go around that I have not touched on...but I wanted to share this because this is some of the things that I learned when I started out. I love what I do now, and I will keep working at it to succeed, and you can too. Good luck!
Worried about your children's education? you can be assured they are not learning what they need to learn, and at this rate, probably never will, unless it is done for them. "no child shall be left behind." That's nice to hear in a specified context, but not for our nation's purpose . if the child fails, they don't have to repeat the grade, "it's alright, they'll eventually learn so pass them." Wrong answer. They implement the standards of learning and expect that children will catch on and it'll be fine, but most children can't or won't pass these tests because they can't pass them or won't pass them due to a growing epidemic called laziness, yet we do nothing to change this.
children are not learning or retaining the education they need to succeed, when they don't, the blame is placed on the teacher, and the school board does nothing to protect or defend the teachers for the students own failure. So now we have the scapegoat and the continuing problem by placing blame on someone else.It wasn't until recently that a very good number of children developed problems such as Attention deficit disorder, learning disabilities, hyperactivity disorders, slow learning disorders or aggressive behavior. Most likely these are all the biggest excuses as to why the average parent has no time to spend with their children, so they call it a disorder and pawn it off on the education system and turn them into babysitters.

(*^__^*) share it with other friends remember (*^__^*) (*^__^*) (*^__^*) (*^__ ^ *)
thousands and thousands of shops
Taobao, Taobao is thousand thousands of products, how to quickly find what they want, mulberry handbags, cheap authentic? Taobao veteran, this is no easy matter, let alone a beginner.
Taobao business was mixed, many of them have bad business sale of counterfeits to deceive consumers. Even a few years my online shopping experiences on the old bird has also been excessive. Some time ago with a friend complained, friends turned a 【Taobao】 internal staff gave me a shopping channel, is said to be former employees leak. After I enter the shopping channel from the inside. The following is the original, we help analyze the credibility of:
If you have been online shopping experience, you must know that Taobao, you know

16, Selected】 【quality shop entrance -
Taobao cheap authentic official recommended a good shop, from here, you can rest assured to buy oh. -
Oh, that's all you, my friend asked me not to tell outsiders (I think that s okay, Taobao so many people; Who knows where to leak out), I hope to help you.
=============================================== =================
I analyzed:
have the following doubts,
1, site why not www.taobao.com, the front also pindao.huoban.taobao.com whether a string of loud noise?
I asked another friend to do the site, he said that the prefix is no problem, above the entrance opening 16 is indeed the official site Taobao page.
2, site no problem, why not open the page Taobao it?
friend said, the internal channel Well, of course, not directly open the home page; if it is in the home, that is not the Earth's people know friends.
3, the shops on these pages, goods are Taobao it?
comparison of my own doing, through these channels into the open the shop and found the shop in Taobao home, shop name is the same, Want Want is the same, the product information is concerned.
Accordingly, I determine the basic is credible; So I bought a tentative 29 dollar T-shirt, also cheated 29 yuan; the results of the seller is very warm, very good service attitude, handbags online cheap, it is quickly get the goods, and cotton, very satisfied! Proven, alexa mulberry, is credible;
(*^__^*) share it with other friends remember (*^__^*) (*^__^*) (*^__^*) (*^__^ *) (*^__^*) (*^__^*) (*^__^*) (*^__^*)

Capacitors is widely used in electronic equipment electronic components, widely used in blocking, coupling, bypass, filtering, tuning circuits, energy conversion, control circuit and so on. Expressed with C capacitance, farad capacitor unit (F), microfarad (uF), Pi Fala (pF), 1F = 10 ^ 6uF = 10 ^ 12pF
one capacitor type nomenclature
; domestic capacitor models generally consists of four parts (not for pressure-sensitive, variable, vacuum capacitor.) In turn represent the name of the material, classification and serial number.
Part I: names, letters, capacitor C.
Part II: materials, with letters.
Part III: Classification, general use digital said that individual with the letters.
Part IV: serial number, use numerals.
material products with letters: A-tantalum electrolytic, B-polystyrene and other non-polar films, C-high-frequency ceramic, D-aluminum, E-electrolysis of other materials, G-alloy electrolysis, H- composite media, I-glass glaze, J-metallized paper, L-polyester polar organic thin film, N-niobium electrolysis, O-glass membrane, Q-film, T-low-frequency ceramics, V-mica paper, Y- Mica, Z-paper dielectric
Second, the classification of the capacitor
1, in accordance with the structure into three main categories: fixed capacitors, variable capacitors and trimmer capacitors.
2, classified by the electrolyte are: organic dielectric capacitor, inorganic dielectric capacitor, electrolytic capacitors and air-dielectric
quality capacitors.
3, divided by end-use: high-pass, low pass, filtering, tuning, high coupling, low coupling, alexa mulberry, small
capacitors.
4, frequency bypass: ceramic capacitors, mica capacitors, glass, film capacitors, polyester capacitors, glass capacitors
enamel device.
5, low frequency bypass: paper capacitor, ceramic capacitor, electrolytic capacitors, polyester capacitors.
6, filter: electrolytic capacitors, paper capacitors, composite paper capacitor, wet tantalum capacitors.
7, tuning: ceramic capacitors, mica capacitors, glass, film capacitors, polystyrene capacitors.
8, high-frequency coupling: ceramic capacitors, mica capacitors, polystyrene capacitors.
9, low coupling: paper capacitor, ceramic capacitor, electrolytic capacitors, polyester capacitors, solid tantalum capacitors
device.
10, small capacitors: metallized paper capacitor, ceramic capacitor, electrolytic capacitors, polystyrene capacitors, solid tantalum capacitors, glass glaze, capacitors, handbags online cheap, metallized polyester capacitors, polypropylene capacitors, mica capacitors.
three commonly used capacitors
1, electrolytic capacitors
electrolyte paste with water soaked paper clip in the middle of the winding and the two foil Cheng, thin oxide film as the medium of the capacitor. because the conductive oxide film are one-way nature, electrolytic capacitors have polarity. capacity, can withstand a large pulse of current, capacity error, leakage current; not suitable for general In the high-frequency and low temperature applications, should not use frequencies above 25kHz low-pass, signal coupling, power supply filtering.
capacity :0.47 - 10000u
rated voltage :6.3 - 450V
main features: small size, capacity, loss of big, big
leakage applications: power supply filtering, low-frequency coupling, decoupling , bypass
2, tantalum electrolytic capacitor (CA) niobium electrolytic capacitors (CN)
made of sintered tantalum anode block, the use of solid manganese dioxide electrolyte temperature characteristics, frequency characteristics and reliability are better than normal electrolytic capacitors, especially the leakage current is very small, the storage of a good, long life, capacity, error is small, and small size, the unit can get the maximum volume under the product of the capacitor voltage tolerance of the ripple current poor, if the damage was easy to short-circuit condition in the ultra-small high-reliability parts.
capacity :0.1 - 1000u
rated voltage :6.3 - 125V
main features: loss, leakage less than electrolytic capacitors
applications: in the demanding circuit in place of aluminum electrolytic capacitors
3, film capacitors and paper capacitors
structure similar, but with polyester, polystyrene and other plastic materials for medium frequency low-loss characteristics, and dielectric loss can not make a large-capacity, poor heat filter, integral, oscillations, timing circuits.
a polyester (PET) capacitor (CL)
capacity: 40p - 4u
rated voltage :63 - 630V
main features: small size, large capacity, paul smith uk, heat humidity, stability poor
applications: less demanding on the stability and the loss of low-frequency circuit
b polystyrene capacitor (CB)
capacity: 10p - 1u
Rated voltage: 100V - 30KV
Main features: stable, low loss, larger
applications: loss of stability and require a higher circuit
c polypropylene capacitors (CBB)
capacity: 1000p - 10u
Rated Voltage :63 - 2000V
main characteristics: performance and polystyrene similar but small in size, stability, slightly worse
applications: most of polystyrene or mica instead of capacitors, used to require higher circuit
4
feedthrough ceramic capacitor or ceramic capacitor pillar structure, which is an electrode mounting screws. Minimal lead inductance, frequency characteristics, and dielectric loss, a temperature compensation can not make a large capacity, the capacity change caused by the vibration will be particularly suitable for high frequency bypass.
a high-frequency ceramic capacitor (CC)
capacity :1 - 6800p
rated voltage :63 - 500V
main features: high-frequency loss, good stability
Application : High frequency circuit
b frequency ceramic capacitor (CT)
capacity: 10p - 4.7u
Rated voltage: 50V - 100V
main features: small size, low cost, big loss , poor stability
applications: less demanding low-frequency circuit
5, monolithic capacitors
(multi-layer ceramic capacitor) in a number of films on the ceramic thin film coating to the electrode paddle blanks material, a composite formed after the first round indivisible whole, the outside envelope made of resin and then a small volume, large capacity, high reliability and a new type of high temperature capacitors, high frequency dielectric constant also has a stable monolithic capacitors performance, small size, Q values of high-capacity larger error noise bypass, filter, integral, oscillating circuit.
Capacity range: 0.5PF--1UF
pressure: two times the rated voltage.
large capacity, small size, high reliability, capacity and stability, high temperature and good humidity.
Applications: Widely used in electronic precision instruments. A variety of small electronic devices for resonance, coupling, filtering, bypass.
6, paper capacitors
two aluminum foil is generally used as the electrode, separated by a thickness of 0.008 ~ 0.012mm overlapping winding capacitors are separated from paper. Manufacturing process is simple, cheap, can get a larger capacity
generally low-frequency circuit, usually not more than 3 ~ 4MHz frequency on the use. Oil capacitor voltage capacitors than ordinary paper, stability Ye Hao, suitable for high voltage circuit.
7, trimmer
capacity can be adjusted within a small range, and can be adjusted to a fixed capacitor value. Ceramic trimmer capacitors of Q value is high, the volume is also small, usually tubular and the wafer can be divided into two. Mica and polystyrene media usually use spring-East, simple structure, but less stable. Wirewound ceramic trimmer capacitors are removed copper to changes in capacitance, so capacity can only be smaller, not suitable for the occasion to be used over and over again.
a

four main characteristics of the capacitor parameters
1, nominal capacitance and tolerance
nominal capacity is a sign of the voltage on the capacitor capacity.
capacitor and the nominal effective capacitance, said capacitance deviation error said the allowed deviation range accuracy.
accuracy class and the permissible error corresponding relationship: 00 (01 )-?%, 0 (02 )-?%, Ⅰ -?%, Ⅱ -? 0%, Ⅲ -? 0%, Ⅳ - (+20% -10%), Ⅴ - (+50% -20%), Ⅵ - (+50% -30%)
General capacitors used Ⅰ, Ⅱ, Ⅲ grade, electrolytic capacitor Ⅳ, Ⅴ, Ⅵ level, according to Use selected.
2, rated voltage
rated at the lowest ambient temperature and ambient temperature can be continuously added to the maximum DC voltage capacitor RMS, the general case directly marked on the capacitor, if the resistance of the capacitor voltage exceeds pressure, capacitor breakdown, resulting in irreparable permanent damage.
3, insulation resistance
DC voltage is applied to the capacitor, and generate leakage current, the ratio is called the insulation resistance.
When the capacitor is small, depending on the surface state capacitance capacity> 0.1uf time, depending on the performance of the media, the bigger the better insulation resistance.
capacitor time constant: for the proper evaluation of large-capacity capacitors to the insulation and the introduction of a time constant, and he is equal to the capacitor insulation resistance and capacity of the product.
4, loss
capacitor electric field, internal heat in unit time is called the loss of the energy consumption. Various types of capacitors are provided in a frequency range to allow the value of the loss, capacitor loss mainly by dielectric loss, mulberry bag, conductivity and capacitance loss of all metal parts caused by the resistance.
in the electric field under the effect of the loss of the capacitor to drain the form of derivative losses, generally small, in the alternating electric field, the capacitance and leakage losses not only lead, but also to establish the periodic polarization processes.
5, frequency
increased with frequency, capacitance of the capacitor general downward pattern.
V. capacitor capacity marked
1, direct standard method
