Reading s*** like that from a book when it comes to human behavior doesn’t work because every once in a while you meet a mother fucksr like me where those rules don’t apply. Maybe to your average mindless dumbass, yeah. Not me.
It’s most important thing is to be yourself, feel good about it, be confident in it, don’t listen to what anyone thinks about it, stay on track and you will attract the right people. Be real and be honest. UNLESS your real and honest it stupid, goofy, in bad taste, generally unattractive. That’s what you will attract.
