Know yourself

“You must determine where you are going, so that you can bargain for yourself, so that you don’t end up resentful, vengeful and cruel. You have to articulate your own principles, so that you can defend yourself against others’ taking inappropriate advantage of you, and so that you are secure and safe while you work and play. You must discipline yourself carefully. You must keep the promises you make to yourself, and reward yourself, so that you can trust and motivate yourself. You need to determine how to act toward yourself so that you are most likely to become and to stay a good person. It would be good to make the world a better place.”
