Don't fear the unknown. In order to be successful, you're going to have to step out of your comfort zone at some point. All successful people must experience this. Find the positive in every situation in which you make this forward movement. View every obstacle as a learning experience.

You can never "fail", as long as you learn something from your efforts. And most people learn more from their perceived "failures" than from their successes Personally, I've found that 99.9 percent of the time, what I worry about never happens. Don't waste time worrying.

Take networking.

Networking can be a terrifying experience for some. While it might not seem quite that horrible to you, for many it can be. But just like anything else, the more you put yourself out there, force yourself to confront your fear, the easier it becomes. And most likely, it won't be half as bad as you thought it would be. Who knows? You might even enjoy yourself! Imagine that!
