Happy Quote
"Is it possible that you’re just not good enough? That you (or your team) just don’t have enough talent to be the best in the world? Sure, it’s possible. In fact, if your chosen area is the cello, or speed skating, then I might even say it’s probable. But in just about every relevant area I can think of, no, it’s not likely. You are good enough. The question is, will you take the shortcut you need to get really good at this?"
-Seth Godin. His latest book The Dip is about dealing with (wisely quitting, or deftly overcoming) that stage, after the euphoria of starting, when your venture gets really hard.
