Being a successful entrepreneur is tricky. You have to live with having control and not having control at the same time. It’s like this: In big business, when you need to cross a river, you simply design a bridge, build it, and march right across.

But in a small venture, you must climb the rocks. You don’tknow where each step will take you, but you do know the generaldirection you are moving in. If you make a mistake, you get wet. Ifyour calculations are wrong, you have to inch your way back to safetyand find a different route.

And, as you jump from rock to slippery rock, you have to like the feeling.
