keeping your commitment becomes hard, you have two choices: You can change your behavior to match your commitment, or you can lower your values to match your behavior. One choice will strengthen your integrity; the other will diminish it and erode your confidence in your ability to make and keep commitments in the future. In addition, that shift in direction with regard to values--even if it's slight--will create a change in trajectory that will create a far more significant difference in destination down the road.
