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

I was an All-American in wrestling in high school, was National Champion in Chinese kickboxing in 1999 and have spent a lot of time around professional athletes, which includes my eight-plus years as CEO of a sports nutrition company.

The least-crowded channel for meeting high profile bloggers is in person. Email is the most difficult, the most crowded... I'm a top 1,000 blogger, not a top 100 blogger, and I get hundreds of pitches by email every week. Most of them I don't even see because my assistant declines them.

The first thing I would do for anyone who's trying to lose body fat, for instance, would be to remove foods from the house that he or she would consume during lapses of self-control.

Most people are fast to stop you before you get started but hesitate to get in the way if you're moving.

If you don't have time, you don't have priorities.
