I like work/life separation, not work/life balance. What I mean by that is, if I'm on, I want to be on and maximally productive. If I'm off, I don't want to think about work. When people strive for work/life balance, they end up blending them. That's how you end up checking email all day Saturday.

If you walk into any bookstore, you can look at the newsstands and see which magazines are nationally-distributed, and you recognize certain names. Same with television. With the blogsphere, however, you actually have to dig, and know how to use multiple tools to figure out whom you should be speaking to.

If you do something as simple as 15-minute ice baths three days a week, and you time those baths properly, you can significantly multiply your fat loss.

One of the great things about stargazing is that it's immediately at hand for so many people. You know, you could get into scuba diving or bird watching, but the stars are always up there.

I might seem biased, but I use Evernote every day. It came to me through my readers, who I'd asked for software recommendations via Twitter and Facebook. For seemingly every function, the answer was 'Man, you have to use Evernote.'

If you start out with a little telescope observing the stars and you keep at it over the years, as I have, it's kind of a dream to one day have an observatory where you can always go and use the telescope conveniently.

The more books there are on shelves, the more will be sold. Once you get to the level of The Secret and have 40-100 copies in many stores, managers have almost no choice but to put them in prime real estate like front-of-store, end caps, or front window.

If retirement means laying on a beach and rubbing coco butter on your stomach, about 48 hours of that will be enough for most people. You'll want something new.

I used Evernote almost exclusively for researching 'The 4-Hour Body.' I was able to eliminate all of the perpetually open tabs and multiple bookmarking services. It's also all automatically backed up to Evernote, which gives me peace of mind.

Workaholics typically have a lot of achievement with very little appreciation of what they have, whether it's cars or friendships or otherwise. That is a shallow victory. Then you have people with a lot of appreciation and no achievement, which is fine, but it doesn't create a lot of good in the world.
