The Value of Persistence
With it, you can move mountains. Without it, you will accomplish nothing. "It" is persistence. David Lorenzo thinks it's your personal competitive advantage. Well, not quite, at least not persistence alone. But if you have everything else and lack persistence, you'll give up when things get rough. And yes, you can count on it, there will be rough times. Hang in there, and you'll overcome most every obstacle.
