Query: I've used all the techiques taught in this book

I've used all the techiques taught in this book and I'm still masturbating. I don't know if it's me or the book but I let you decide. Although it didn't help me get a chick, it did boost my self-esteem up a bit. I'm feeling more confident about myself now. So this is actually a good self-help book. Probably the most important thing I learned from this book is to not seek validation from anyone but yourself. I used to seek all my validation from being able to find this really hot chick which I never ever did and so I feel [bad] all the time. But now I know it's no big deal...but my hand is getting tired.
