Just had a beer with an old friend of mine who tomorrow morning will quit his job at a publicly-traded Internet company to strike out and start a new business. Not only do I wish him good luck, I must admit a bit of jealousy. There's nothing quite like that moment when you throw caution to the wind and strike out for unknown shores. No matter how it turns out you are almost always the richer for taking the risk and discomfort it entails.
