What do wish you'd known in your 20s that you know now? Please respond!?

Question

whether relationship or career...

Answer 1

"men" are life support systems for penises.

Answer 2

That women are not "sugar and spice, and all things nice" they are as rotten and mercenary as men, and talk about them in exactly the language that men discuss women, Errol Flynn  actually "wired" a women's room  in Hollywood to prove this, ( my hero ), I just wish that I had known all of this when I was 20, years old, I would have treated them with much less manners, or respect,  and probably been much happier, and wealthier too........
