Love is selfish. I can only love you if I genuinely love, value, appreciate, and respect myself. If I am empty, then all I can give you is my emptiness. If I feel that I'm complete and worthwhile in myself, then I'm able to give to you out of my fullness. One of the best ways for me to give you love is by fully enjoying myself with you.
Love involves seeing the potential within the person we love. In my love for another, I view her or him as the person she or he can become, while still accepting who and what the person is now. By taking people as they are, we make them worse, but by treating them as if they already were what they ought to be, we help make them better.
