You are so anxious about the future that you do not enjoy the present. You therefore do not live in the present or the future. You live as if you are never going to die, and then die having never really lived.
Dalai LamaIf 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.
Dalai Lama
