How can I improve my success with women?

I am a guy in college with a lot of great looking girls. I was in a relationship with one but it didn’t work out and I am really interested in starting another relationship with one. I dress alright I suppose but its my conversation skills and my quiet nature that I think is hindering me. Does anyone out there have some great tips that can help me improve my success with women? Are any of you fluther guys out there consider yourselves a player, have or had enormous successes with women?
