Don’t follow a model that doesn't work. If the recipe sucks, it doesn't matter how good a cook you are.

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.

If you look at the purported dangers of salt or fat, there is no consensus of support in scientific literature. So I would ask first: 'Is it possible to have an informed government that actually follows the science?' From what I've seen, it's not likely.

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."

The problem with New Year's resolutions - and resolutions to 'get in better shape' in general, which are very amorphous - is that people try to adopt too many behavioral changes at once. It doesn't work. I don't care if you're a world-class CEO - you'll quit.

The way that you become world-class is... by asking good questions.
