Probably 90 percent of our life decisions are powered by the twin engines of inertia and laziness.

I tried the paleo diet, which is the caveman diet - lots of meat. I tried the raw food vegan diet. And I tried the calorie restriction diet, which is the idea is that if you eat very, very little - if you're on the verge of starvation, you will live a very long time. Whether or not you want to, of course, is the idea.

A few weeks later, I’m in a fluorescent-lit classroom in Chelsea awaiting the start of the official Mensa test. I’m sitting next to a guy who’s doing a series of elaborate neck stretches, like we’re about to engage in a vigorous rugby match. He’s neatly laid out four types of gum on his Formica desk: Juicy Fruit, Wrigley Spearmint, Big Red, and Eclipse. I hate this guy. I hope to God he’s not a genius.

I've never before been so aware of the thousands of little good things, the thousands of things that go right every day.

This is what the Sabbath should feel like. A pause. Not just a minor pause, but a major pause. Not just lowering the volume, but a muting. As the famous rabbi Abraham Joshua Heschel put it, the Sabbath is a sanctuary in time.

My goal? To test out every diet and exercise regimen on planet earth and figure out which work best. I sweated, I cooked, I learned to pole dance. In the end, I lost weight, lowered my cholesterol and doubled my energy level. I feel better than I ever have.

The year showed me beyond a doubt that everyone practices cafeteria religion... But the important lesson was this: there's nothing wrong with choosing. Cafeterias aren't bad per se... the key is in choosing the right dishes. You need to pick the nurturing ones (compassion), the healthy ones (love thy neighbor), not the bitter ones.
