Setbacks and fear are inevitable. The thing that distinguishes the ultimate successes from the ultimate failures is this: What do you do with them?

The most important step of all is the first step. Start something! What if that idea you have in the back of your head is a really good one, one that might end up helping tens of thousands of people? You owe it to the world ot act. Or maybe it will help only a few people: The same advice applies. If you don't do it, you are missing out on something big, and so are the people who could have been helped.

Keep it simple: own as little as you can get away with, schedule everything, keep a notebook, don't let technology enslave you.

When you incorporate giving into your business in an authentic and transparent way, your customers become your best marketers.

The more you give, the more you live.
