“Being a man is not a matter of whether hair grows on your chin, lad. It's inside your head. Some males never make it at all. Being a man is rolling up your sleeves and telling the world 'Now I'll play by the real rules—no more wooden swords. If I succeed, then the credit belongs to me, not my parents or teachers or employers, and I shall savor the prizes without guilt, knowing I earned them. And if I fail, then I'll pay the penalties without whimpering or blaming anyone else.' That's what manhood is,”
― Dave Duncan, Magic Casement

“If you fulfill your obligations everyday you don't need to worry about the future.”

“What is your friend: the things you know, or the things you don't know. First of all, there's a lot more things you don't know. And second, the things you don't know is the birthplace of all your new knowledge! So if you make the things you don't know your friend, rather than the things you know, well then you're always on a quest in a sense. You're always looking for new information in the off chance that somebody who doesn't agree with you will tell you something you couldn't have figured out on your own! It's a completely different way of looking at the world. It's the antithesis of opinionated.”
― Jordan B. Peterson

“If you can't understand why someone is doing something, look at the consequences of their actions, whatever they might be, and then infer the motivations from their consequences.

For example if someone is making everyone around them miserable and you'd like to know why, their motive may simply be to make everyone around them miserable including themselves.”
― Jordan B. Peterson
