when you love what you do for work is whether you’re going to be a peak performer or a workaholic. Charles Garfield made this distinction for me years ago: Workaholics never know how to shut the motor down. They sneak their cell phones onto the golf course. When they are home, they are never really home. On the other hand, peak performers might work twenty-eight hours a day for a period of time, but then they shut the motor down and do something else. They will stay in the car in their home driveway
