" All of us regularly say yes unthinkingly, or out of vague attraction, or out of greed or vanity. Because we can’t say no—because we might miss out on something if we did. We think “yes” will let us accomplish more, when in reality it prevents exactly what we seek. All of us waste precious life doing things we don’t like, to prove ourselves to people we don’t respect, and to get things we don’t want. "
