A “turtle step” is my label for the largest possible task that your essential self can do easily. That last word—easily—is very, very important. We’re not talking about how much you can do when you’re pushing a deadline, ignoring all other responsibilities, fueling yourself with gallons of caffeine, and receiving a fortuitous visit from the muse. Even on a bad day, when you contemplate your turtle steps, your immediate, genuine gut reaction should be, “Oh, yeah, sure. I can do that.”
