For the last two months, I’ve been sleep-deprived and generally exhausted. (A newborn has arrived.) The best solution? Manage a business, launch a second business, and exercise a lot.

My new son takes the same approach. If he sleeps a lot during the day, he’ll sleep a lot that night. (The opposite is also true.) Sleep makes sleep. Action makes action.

A lot of us wait until we’re inspired before we write, wait until we’re confident before we sing in public, wait until we’re rested before we start running intervals. As a result, we become worse writers, worse singers and worse athletes.

Feeling sad? Laugh. Feeling tired? Go for a run. Feeling intimidated? Commit.

Don’t wait until you feel like it. You won’t feel like doing it until you’ve done it. But then you’ll feel like doing it again. Unlike money, the best way to get more energy is to spend energy.
