There's some real gems mixed in with some fairly mundane stuff.

I would summarize the good stuff like this:

Try to understand how evolution works, because you are a product of it. What you like to eat, what you like to do, who you want to hang out with, why you feel good or bad when {situations} happens.

But don't be a slave to it. Yes, there is a pressure to be the alpha male. Yes, you will get angry when people cheat you. But you are not a meat machine, you are still a person that can respond to the world with your own agency.
