“If you exchange a penny for a dollar, it is not a sacrifice; if you exchange a dollar for a penny, it is. If you achieve a career you wanted, after years of struggle, it is not a sacrifice; if you then renounce it for the sake of a rival, it is. If you own a bottle of milk and give it to your starving child, it is not a sacrifice; if you give it to your neighbor’s child and let your own die, it is.
