I'm going to preface this with saying I do ok.

I'm still in the "Holy shit, this PUA stuff actually works!" stage. I'm not fantastic, but I do alright. I can get hot girls into me occasionally (I had this SUPER hot girl flirting with me all night. She was hot so I opened her with calling her a trashy whore) - but I rarely close. I even had guys trying to talk to me and admiring how I was doing with women, but once again, while I can keep a conversation going (sometimes, I'm better at this but it sucks sometimes), I very rarely close (numbers about 30% of the time - I barely ask, and fucking almost never).

I do some escalation, I make out frequently enough, but like, I don't know how to seal the deal.

What are the best ways to practice this? I was considering just practicing on less attractive girls, and closing them repeatedly to get my feet wet.
