This is a variation on the theme, that when training for sports, the best thing you can do is to work the weakest areas, not the strongest ones, or to win a football game it really goes a long ways to simply not turnover the ball or let the other guys have big plays. There was also this theme in the book "Willpower" where it talks about how everyone fails in their willpower at some point, but the real key is to limit the damage of said failure - if dieting, for example, and you break down and stuff a chocolate bar in your face, the key is stop after the one bar, and not just spiral and "since I already failed" stuff your face with bon bon's and a bowl of ice cream and...... Acknowledge you slipped up, then get back on track.
