I would advise you to go out and stop being home so much and stop playing video games and shit.The more you are out ,the better chance you have at meeting girls and getting social skill.Go to cool events like dj night at a popular club,bars,concerts ,parties,college clubs,social events ,farmers markets ,and places filled with people and hot girls in general .The more I started going out in college the more I learned how to get girls.I was just very observant and saw guys who were successful and copied some of there lines,style and confidence.Even if you go by yourself and just be in that atmosphere you will grow in the world of getting women and socializing.Dont be 45 and regret not doing shit and having fun when you were 22 and always home.
