By going beyond your own problems and taking care of others, you gain inner strength, self-confidence, courage, and a greater sense of calm.
One hot afternoon during the era in which you've gotten yourself ridiculously tangled up with heroin you will be riding the bus and thinking what a worthless piece of crap you are when a little girl will get on the bus holding...two purple balloons. She'll offer you one of the balloons, but you won't take it because you believe you no longer have a right to such tiny beautiful things. You're wrong. You do.
