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.
Do what you love to do and give it your very best. Whether it's business or baseball, or the theater, or any field. If you don't love what you're doing and you can't give it your best, get out of it. Life is too short. You'll be an old man before you know it.
What is perfection in love? Love your enemies in such a way that you would desire to make them your brothers ... For so did He love, Who hanging on the Cross, said "Father, forgive them, for they know not what they do." (Luke 23:34)
