Entrepreneurs need to stop thinking so much and start acting, advises New York VC Fred Wilson. Call it "analysis paralysis" or the "Hamlet complex" or whatever you want, but the fact remains that it's impossible to analyze every action and every possible contingency before making an important decision. Venture backers will applaud an entrepreneur who acts and takes risks, even if the action turns out to be misguided later, says Wilson. As Teddy Roosevelt once said:

"In any moment of decision the best thing you can do is the right thing, the next best thing is the wrong thing, and the worst thing you can do is nothing."
