Models is some decent dating advice, with a garnish of pickup artist bullshit.

The basic thesis is that the details are different for everyone, in general we all want emotionally cohesive real relationships. Which if you're a man, means somewhat contradictorily, vulnerability. You have to be honest with yourself and other people, because only by being vulnerable can you demonstrate real strength and not merely brittle machismo. A second point is that you want to be polarizing, because you can't please everyone, so you want to get prospective dates to either like you or tell you to piss off so you don't waste your time. And the third point is to initiate action, because rejection happens and your anxiety about rejection is frankly the biggest barrier to getting laid.

The steps to not being an unfuckable mess are pretty simple. Hit the gym, get some new clothes and a haircut, develop at least one social hobby, and find a job you like. Then, having worked on yourself, start approaching women socially with a simple "Hello, I think you're cute. What's your name." and see where things go. This gets into the less good PUA part of the book, but, fact is you have to get out there to get dates, and rejection is part it. Just don't be insistent or overly weird. And for dates, movie dates are awful, dinner dates bad, try to plan three linked activities with plenty of time for talking, and make statements to keep the conversation going. Physical touch is key, starting with the hands and then moving towards more intimacy (which has some nasty contradictions with consent, but so it goes.)

Short, clear, and reasonably ethical, this is one dating advice book which holds up.
