If you're trying to serve someone in need and it doesn't hurt a little, you're doing something wrong. Sure, it's nice to lend a helping hand, but true compassion causes your heart to break - even at the moment you're helping...When people say the only reason to help the less fortunate is so you can feel better about yourself, I laugh. Those people obviously have never lived among the poor, the destitute, the heartbroken. They have never put themselves out there and truly suffered with someone in pain. This idea that philanthropy is self-medication is not true; in fact, it's so outrageous that it's laughable. If you're really helping someone in pain - if you're really experiencing compassion - you can't help but hurt too.This is the litmus test for those aspiring to make a difference in others' lives: Do we feel cheery about the work we're doing, or does it hurt a little, maybe even a lot? If the latter, you're on the right track.
