I am quite new to the game but so far I have realized that being confident is not enough to get women. What we men need is to be an Alpha Male and being confident is just part of it. Alpha Males get what they want be it women or anything else.
I personally see big improvements in my social, work and dating lives just by getting more confidence in myself and by improving the way I dress, look and behave. You may not end up having sex with super models but you definitely will attract more respect, more attention and more people.
