This brings me to the second part of the Hard Thing Rule: You can quit. But you can’t quit until the season is over, the tuition payment is up, or some other “natural” stopping point has arrived. You must, at least for the interval to which you’ve committed yourself, finish whatever you begin. In other words, you can’t quit on a day when your teacher yells at you, or you lose a race, or you have to miss a sleepover because of a recital the next morning. You can’t quit on a bad day.
