Thanks for the A2A
The book I remember the most that I’ve referred to in my head the most is The Art of Seduction: 33 Laws of Persuasion by Robert Greene. I’ve found it the most useful of his books by far. It’s mostly about not doing what everybody else does, and that’s incredibly useful when it comes to being attractive. Don’t let the title fool you, it’s an excellent book.
I’ve also really enjoyed Leil Lowndes’s books as well.
