打开成功之门的钥匙
Your Key to Certain Success
佚名 / Anonymous
One of the most important attributes an individual can have is confidence. Confidence is invaluable in every area of life， but in business or in achieving any degree of greatness， it is absolutely essential. Unfortunately， there are few places we can go to learn this essential skill. Yet， it is a skill and， as such， can be developed with the right tools.
The first tool for gaining confidence is knowledge. Knowledge of your own strengths and limitations， and knowledge of the arena in which you wish to excel. But knowledge alone isn' t enough. Knowledge leads to confidence only when it is validated by experience. We test the validity of what we think or believe by putting the theory into actual practice and gathering data or feedback from the experience. If the feedback is positive， we assume our theories are correct and act accordingly. If the feedback is negative， the bold among us will adjust our course， while the more timid often allow the negative feedback to stop them cold.
Confidence can be gained by knowing， understanding and correctly applying the following formulas and factors：
(1) Knowledge + Experience + Positive Feedback = Confidence.
(2) Positive feedback comes from successful outcomes.
(3) Successful outcomes are the result of consistent practice and repeated attempts.
(4) Repeated attempts are possible only when we believe we will eventually succeed.
