Be thoughtful and honest with yourself about your missteps, but don’t start dwelling on them. People beat themselves up and obsess about something that happened thirteen years ago—a business partnership that didn’t work out, a startup that failed, or a boss they didn’t like—and it becomes the jail they live in. With all the time you have left, there’s zero value in getting bogged down there. If I ever get into that mud, I’m grabbing my gratitude hose to wash it off.
