Willpower is overrated. Rather than relying completely on self-control, intentionally design your environment to make the hard thing easier. For example, if you (like everyone) are constantly distracted by your smartphone, don’t just turn it off — remove it altogether from where you’re trying to concentrate. If your challenge is eating healthy, instead of relying on your willpower at 9 p.m. after a glass of wine, simply keep the brownies out of the house. This applies to everything. Don’t just think about how you’re going to accomplish your goals; think about how you’re going to design for them.
