I'd love to get ideas on overcoming jet lag.

I've seen Leonardo Da Vinci notebooks which are filled with tiny, messy scrawls written in mirror image across the page. I'd love to know how he kept all his projects going at once.

There are a lot of ideas I've had that I originally was quite taken with, but over time, I lost steam. They stay on my list, but between me and you, I'm probably never going to do them.

I specialize in science and history, with a special emphasis on including do-it-yourself projects in the mix. My dozen or so books have sold hundreds of thousands of copies. I'm also a contributing editor at Popular Science and at Make Magazine.

Yeah, it's a weird little niche, but by God, it's my niche.

You get energy from other people, so hang out with energetic people.

In my home office, I built a custom sit-stand desk to which I connected a big, kidney shaped glass top which I got for cheap at Ikea. Kidney-shaped desk tops are, I think, the most efficient of all possible desk shapes.
