(By Gil Gerretsen) Many self-made billionaires were fired from established companies early in their careers. Many others resigned from companies in their field of choice, typically out of frustration because the company moved too slowly, was too antagonistic towards their ideas, or simply bored them. It's a common outcome since most existing companies are set up to optimize what has already been created. Few have the capacity to once again disrupt their own creation.

What is unique is their ability to shrug off rejection. They see themselves as being actively in control of their own destiny, and as a result, learn to move on quickly. Situations affect them but don't hinder them. They remain self-confident and are not easily discouraged. They are able to deal with setbacks because they primarily see those events as feedback. They heed the lessons of failure and learn from their mistakes without making any excuses. Setbacks are feedback, not terminal failures.

As they move forward, self-made billionaires monetize their mistakes by making calculated risks by trying a number of different ideas over a long period. They believe that experimentation will lead them to their sought-after solution. To them, it's a numbers game. By exploring a number of different options, they are more likely to succeed than their neighbor, who only starts one company or pursues a single business idea over their life. Recognize that people don't remember failure. They remember good.
