The enjoyment that comes from our acts of kindness give us a glimpse of the world that might be, hopefully our future world. Good natured, friendly, human.
Take up giving-away as a hobby while you are young, and you will have a happy life. What is more, because you do so many thoughtful things on impulse, you will develop a lively and interesting personality- gracious, friendly, and likeable.
The secret of successfully giving yourself away lies not so much in calculated actions as in cultivating friendly, warm-hearted impulses. You have to train yourself to obey giving impulses on the instant -- before they get a chance to cool. When you give impulsively, something happens inside of you that makes you glow, sometimes for hours.
