The difference between a goal-directed individual and someone without goals is like the difference between a Wimbledon champion and a kid batting a tennis ball around on a court with no net, no opponent to bring out the best in him, and no way of keeping score.
Let others lead small lives, but not you. Let others argue over small things, but not you. Let others cry over small hurts, but not you. Let others leave their future in someone else's hands, but not you.
