From the Book, Make Today Matter, by Chris Lowney:

“Don’t treat your life as a race to be won. Don’t focus on getting to the top of the heap, because every peak you reach will yield a clearer view of the next summit, already occupied by another competitor in the game of life. Run every race as if it’s your last, but decide first why you’re running. Instead of competing against me or anyone else, why not contribute your energies to making us better people, through your coaching, love, inspiring example, or noble mission? Instead of trying to win the race, why not make it your mission to contribute to the race, the human race—by making your corner of the world more just, more loving, and more happy.”
