To succeed as an entrepreneur, you need to conquer your fears and self-doubt -- or at least do a good job of hiding them, writes investor Fred Wilson (avc.com):
"You simply can't be tentative in a startup. You have to go for it at every chance you get. And if the leader of the organization is anxious, his or her fear pervades the organization. Everything comes from the top in a company.…So if you are starting a company or building one, face your fears and move past them. It's critically important to your company."
