"People who tell themselves, 'not now, but later,' are generally less tormented by the temptation of something they are trying to avoid," writes Baumeister. Keep this in mind when enjoying your weekend down time—while we're all about relaxing and living in the moment, you'll thank yourself for thinking long-term come Monday morning.
