Another book i would recommend is Level Up by James D. Wolfe. It's not pick up related at all (although aspects of it do touch on interacting with women) but its a book more about improving your confidence, self love & self esteem & how to identify & eliminate self limiting beliefs.

Admittedly I've not finished it but from a personal development point of view it pretty much has everything i was looking for within 1 book. Though as the other guys have said, don't concentrate too much on theory for now.
