For most of my life I've been an anti-social loser. Always had a hard time making friends in HS/college. Spent my time smoking weed, playing video games, masterbating to porn, you name it. As a result I was content and never stepped outside to make friends or meet girls. In junior year of college I ended up dating a 5/10 chubby girl for two years because I was desperate for sex, essentially.

I've only recently begun to embrace the red pill, but I feel like I'm very late. I'm already a graduating senior at my college. I've made no friends, still hang out with my stoner friends from HS. I'm slowly beginning to break my old chains, but the path seems very difficult. I have a semi-secure job at a mortgage company working part time, I'm getting my degree in economics this may, and I've been lifting at least 3x a week. I'm also tall and relatively attractive according to a lot of girls, however I am still almost cripplingly shy.

My biggest obstacle is having no social circle. I've had some success recently from getting girls numbers, but I haven't been aggressive enough and since I'm still young the fact that I have no social media to speak of really hurts my perception among girls.

Where can I start to develop a social circle? I never joined any frats/clubs at school. Now it's late, and I'm about to lose college as my resource.
