Enlightened self-interest that looks like altruism

Add these three elements together, and you will start behaving in a manner that others interpret as altruism. You will exhibit a strong interest in your community, peers and colleagues, because doing so is how you make the formula work on your behalf.

Here's the critical part: you must adopt all three! If you adopt just one, your life won't go so well.

If you just focus on pleasure, you'll end up with a superficial and unsustainable life. If you simply avoid pain, you'll never accomplish anything worthwhile. If you obsess with your self-interest, you'll become the greedy and selfish person I promised to help you avoid becoming.
