I'm always interested in what tools highly successful people use to do their work. While the tool itself can't magically do the work (as Seth Godin reminds us), top performers have usually thought more about tool selection than the rest of us, and we can often learn something from them. Exhibit A is George R.R. Martin, author of A Song of Ice and Fire (on which Game of Thrones is based) and one of the most successful living authors.

Ever run out of clean underwear? Happened to me a few weeks ago. It was almost time to leave for work, so I had only one option. “Woe is me!” I thought, as I plucked the previous day’s pair from the laundry pile, thoroughly grossed out. Since then, I’ve read Endurance by astronaut Scott Kelly, and it’s helped me adjust my perspective on dirty underwear and hardship in general. Kelly spent nearly a year on the International Space Station (340 days, to be exact), and he wore each pair of underwear up to four days in a row.

Like regular exercise, sufficient sleep, and many other things that are good for us—and science increasingly shows that gratitude is good for us, both psychologically and physiologically—it’s easy to recognize the value of gratitude yet fail to make it part of our daily lives.

A couple months ago, Sarah and I were hanging out with four close friends, three of whom have graduate degrees in mathematics. (For someone with no advanced math chops, I seem to get along great with people who do. Maybe I figure they can cover for me if some sort of math emergency arises.) At one point in the conversation, I asked the group one of my favorite questions: “What do you wish ‘regular’ people knew about your field?

My niece, Emma, gave a TEDx talk last Sunday. Giving a TEDx talk is an honor, especially for a college sophomore. But what I find most impressive isn’t the fact that she gave a TEDx talk—it’s that she applied to give one in the first place. The fact that Emma’s talk was chosen wasn’t in her control. She maximized her chances by submitting an excellent proposal, yes, but she couldn’t directly control whether the selection committee chose her talk.
