I love work, just not hard work.
So I put my laziness to work for me. Instead of long proposals, I wrote short ones. Instead of worrying about competitors, I ignored them. And here's what happened: My company got more work. I found better clients. I slept better. I woke up better. I was happier. And, most of all, running a business became a lot easier.
Fifteen years later, this continues to be the most important lesson I've learned as an entrepreneur: Most of the stuff you agonize about just doesn't matter. Truth is, things are pretty easy and straightforward -- until you make them hard and complicated.
