It’s just a matter of mastering the mundane—of repeating simple little disciplines that, done consistently over time, will add up to the very biggest accomplishments. Of course, it’s just as easy not to. But that simple, seemingly insignificant error in judgment, compounded over time, will ruin your chances for success. You can count on it. That’s the choice you face every day, every hour: A simple, positive action, repeated over time. A simple error in judgment, repeated over time. So easy to do. So easy not to do.
