Of course, sometimes just being yourself isn't working with women, so you need external influences. However, becoming a carbon copy of someone else isn't the way to do it. Instead, you must pick and choose what works for you.
Using myself as an example, I was a student of Player Supreme, but I didn't try to be him. I have different views on homosexuality (I have absolutely no problem with being around homosexuals. Afterall, I did date four bi-sexual women who have a lot of homosexual friends.), and the whole coffee shop date thing just wasn't doing it for me.
