The success of love is in the loving - it is not in the result of loving. Of course it is natural in love to want the best for the other person, but whether it turns out that way or not does not determine the value of what we have done.
Whether success or failure: the truth of a life really has little to do with its quality. The quality of life is in proportion, always, to the capacity for delight. The capacity for delight is the gift of paying attention.
Most people tell you they want to get out of kindergarten, but don't believe them. Don't believe them! All they want you to do is to mend their broken toys. "Give me back my wife. Give me back my job. Give me back my money. Give me back my reputation, my success." This is what they want; they want their toys replaced. That's all. Even the best psychologist will tell you that, that people don't really want to be cured. What they want is relief; a cure is painful.
