There is nothing forced or self-disciplined about [generosity] ... [A generous person] goes out of his way not because his parents taught him that's how good [people] behave, but because he has chosen to be alert to the circumstances in which he can be supportive.
Generosity brings happiness at every stage of its expression. We experience joy in forming the intention to be generous. We experience joy in the actual act of giving something. And we experience joy in remembering the fact that we have given.
