If you have only education and knowledge and a lack of the other side, then you may not be a happy person, but a person of mental unrest, of frustration. Not only that, but if you combine these two, your whole life will be a constructive and happy life. And certainly you can make immense benefit for society and the betterment of humanity. That is one of my fundamental beliefs: that a good heart, a warm heart, a compassionate heart, is still teachable.
If you will think about what you ought to do for other people, your character will take care of itself. Character is a by-product, and any man who devotes himself to its cultivation in his own case will become a selfish prig.
When you meet someone better than yourself, turn your thoughts to becoming his equal. When you meet someone not as good as you are, look within and examine your own self.
