" If you devote yourself only to yourself, if your heart strives, above all else, for fame, or money, or power or even happiness, I'm not saying you're a bad person. But you are making a bad choice.
Choose service instead. Not because the world needs you -- it probably doesn't. The world will be fine. And if it won't be fine, you alone can't fix it.
Choose service because there is nothing more insufferable than a talented, driven person who is also completely self-obsessed. Those people are awful. They spend their lives trying to fill a hole and digging it deeper instead. Anyone can be successful. Only service can make you realize how insignificant, and yet how meaningful, your time on earth really is. "
