Re: Introductory and 2 questions :)
Another good book to read would be Mystery Method but it depends a lot on your strengths and weaknesses. So tell us more about that. With the girl your chances of winning her over are not very good since she has strong feelings for your friend that shes slept with. However don't use pua to get a certain girl use it to get more girls in your life. Lastly dhv shows that you're an exciting person and not someone who just wakes up goes to work and watches tv. You show this by telling her an exciting story or showing passion for a hobby. Good Luck and Welcome to the forums
In life you get what you put into it.
