William MacDonald said well, “Just as it is folly for one person to envy another’s gift, so it is equally foolish for anyone to depreciate another’s gift or feel that he doesn’t need the others. The eye cannot say to the hand, “I have no need of you”; nor again the head to the feet, “I have no need of you.” The eye can see things to be done, but it can’t do them. It depends on the hand for that. Again, the head might know that it is necessary to go to a certain place, but it depends on the feet to take it there.”
