“You give a lot, and hope someone returns the favor…and over time, you start to get annoyed, resenting people, and the once giant heart you once gave so freely gets covered in gnarly scar tissue.
You look around, and you see people who are complete jerks with hot women that they don’t deserve, whom you could treat better.”

Giving in the hope of having favours come in return is not true giving. It is manipulating and if it bites you in the ass, maybe that’s a natural outcome. If you give out of an honest friendly well-meaning, and don’t give more than you have, none of this gnarly scar tissue will result. It is up to you whether you start to get annoyed and resent people. And it doesn’t hurt anyone as much as it hurts you when you do.

Hot women are not a prize you “deserve” by treating them well or scoring attractiveness points. They are human beings with their own hopes, dreams, neuroses and reasons for doing things. And this human being right here is moved, for some reason, to point out you sound like a boor in these couple of paragraphs.

Your advice is sound enough, but it sounds like you need it as much as anyone. Good luck with your shifting perspective.
