There are many diamonds in the world and if you lose your favorite, you can work hard, earn a lot of money and get another one to replace it. But the moments of your life aren't like that. Once they're gone, they'll never return. Each and every one is the most precious thing in existence. You can never meaningfully compare one moment with any other. You can never meaningfully compare your life with anyone else's. No matter how rich someone else may be, no matter how happy they look, no matter how enlightened they seem, they can never be you. Never, ever, ever. Only you can live your life
