Slow down and remember this: Most things make no difference. Being busy is a form of mental laziness-lazy thinking and indiscriminate action.

By working only when you are most effective, life is both more productive and more enjoyable. It's the perfect example of having your cake and eating it, too.

Uncertainty and the prospect of failure can be very scary noises in the shadows. Most people will choose unhappiness over uncertainty.

If the challenge we face doesn't scare us, then it's probably not that important.

Simplicity requires ruthlessness.

Doing something unimportant well does not make it important.

There is an infinite selection of things that I could test in life, so I generally will look for a critical mass of word that comes back to me. At this point I have hundreds of friends who are the best at what they do, arguably number one in the country or in the world. I will oftentimes just kind of throw a volley out to people, ask them what they're obsessing on or what they find interesting that's on the fringe. If the same answer comes back a few times, I'm like, "Okay."
