"I don't care if you're a parent giving to a child, a worker to a company, or a romantic to a lover, this behavior eventually leads to resentment. There's always a hidden agenda of What's in it for me? It's often suppressed, and this is why sacrifice is ultimately unwise and incomplete. Does this mean that there's no such thing as altruism, philanthropy, or generosity? No, it just means that anytime these exist, so do egocentricity, misanthropy, and greed. There's always a balancing force, even if it's sometimes hidden or unconscious."
