Rather than spend my life on data entry and typing, I also take photos on my iPhone of business cards, wine labels, menus, or anything I want to have searchable on-the-run.

There are a lot of things that can be learned from the darker corners of athletics. You have doctors who view bodybuilders as cavalier amateurs of science. And then you have the bodybuilders who view the doctors as too conservative to do anything interesting. So I've tried to become the middleman for putting some of those pieces together.

Having a size 9 foot is fantastic because almost all of the shoe companies do their prototyping in size 9, so if you visit a place like Nike headquarters, you can try every sort of wacky, out-there model.

I have scary eyes. I look like the guy in 'American History X,' yes. I remember coming home from school and asking my mum if I could get an eye transplant, and of course she declined.

There's an entire generation of male strength and endurance athletes, even recreational lifters, who have never gotten off the ephedrine-caffeine-aspirin stack. The process of getting off stimulants is really horrible.

After decades of hauling telescopes around in the back of vans and going up to high altitude locations and so forth, I did finally build an observatory, here on Sonoma mountain.

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 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.

It's very easy to confuse confident motion with being productive - and they're not the same thing. Productive to me means measurable outcomes that apply to my most important to-dos that positively affect my life. That's it.

I started using Twitter about year after its very early adoption and ended up investing in it around that same time. I'm involved with the Tech scene and companies ranging from Facebook, Stumbleupon and Twitter.

I do not equate productivity to happiness. For most people, happiness in life is a massive amount of achievement plus a massive amount of appreciation. And you need both of those things.

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.

When I left the U.S. for the first time, I spent my first year abroad in Japan. That culture shock and abundance of new stimuli combined with a lack of guidance forced me to develop my own approaches to learning and juggling.

I still feel there are much smarter self-promoters out there than me. I am very methodical about my messaging, and I know how to gain attention very quickly.

I work hard, but in spurts.

Everything that works in sales has been done already. Just keep track of the crap that you buy, or the awesome stuff that you buy, and decide what was the trigger, and then just sell to people like you. It's really that easy - and that's what I do.

When you elevate the heels more so than you elevate the sole of the foot, you trigger a cascade of compensations in the knees and hips that cause tight hip flexors, and then those hip flexors cause lower-back pain.

I didn't even like white wine. Then I tasted it and bought a case. It was the first case of any wine I'd ever bought.

I still feel there are much smarter self-promoters out there than me. I am very methodical about my messaging, and I know how to gain attention very quickly. David Blaine is an example of someone who's better at self-promoting than me. He is much better than I am.

Writing is thought crystalized on a piece of paper, which can then be reviewed.

As far as income goes, there are three currencies in the world; most people ignore two. The three currencies are time, income and mobility, in descending order of importance. Most people focus exclusively on income.

To make a bestseller, there are more customers than just your customers: Selling to the end-user is just one piece of the puzzle. In my case, I needed to first sell myself to the publisher to get marketing support and national retail distribution.

I'm not a fan of idleness, except in small doses.

You don't have to travel, but I find extended travel to be a helpful tool for reexamining yourself and the constraints you've artificially placed on your life. It's easy to believe everything has to be done one way if you're always in one place around the same people.

I discourage passive skepticism, which is the armchair variety where people sit back and criticize without ever subjecting their theories or themselves to real field testing.
