We can all remember times when we’ve been so engrossed in a project that we skipped breakfast and then worked right through lunch. By three or four in the afternoon your hunger begins to scratch at the insides of your stomach. Just then, you remember you’ve forgotten two meals! What do you do—what’s your response? You wouldn’t say, ‘‘Well, I skipped breakfast, and I breezed right over lunch, so forget it—I’m not eating anymore. After all, I’ve already forgotten two meals—what’s the point?’’ Of course not! You’d look forward all the more to dinner.
