“If quitting is a possibility, everyone will pick that—it’s the easiest one. Who wouldn’t pick not running at 5:00 a.m. over running at 5:00 a.m.? If quitting is an option, you’ll never finish anything hard. The only way an imperfect mind can be forced to achieve is by removing all of its other options. To me, the heart of all successful human interactions is we look at each other and we know we’re about to attempt something that is difficult/impossible, and we both vow to die before we quit.”
