"It is our rarest possession, more precious than any treasure from nature, God, or man. It cannot be bought, sold, traded, or stolen. You only have so much of it, and you never know when it will run out, so you mustn't waste it or just let it pass or, heaven forbid, ever try to kill it. It is Time. Spend your time wisely. For if you can master this one simple and elusive skill, you will fully and truly be alive."
