True giving happens when you are overflowing from the inside, and cannot help but share. When there is so much love within you that it has to flow to others or you would burst open. There is no thinking involved, no willpower in such sharing. It just flows out. If you have to force yourself to be kind, to love, to feel compassion, you've missed the first step of filling in your own Self with these emotions.
This is so true! When I have to force myself to give of myself, it's time to take out the mirror and do some analyzing.
