I don't think that you have any insight whatsoever into your capacity for good until you have some well-developed insight into your capacity for evil. - Jordan Peterson

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.

[…] The quality of our thoughts is actually dependent on our ability to speak our minds.

Much of happiness is hope, no matter how deep the underworld in which that hope was conceived.
