Happy new year r/seduction!

It's a new year and my resolution for this year is to improve my self confidence and get rid of the awkwardness that has plagued the previous 18 years of my life. I was always a bit of nerd, but also not a full on one. I, like many others my age, game too. Until about 2/3 months ago, gaming has fucked me up good. I never knew moderation so therefore, I never improved my social skills. I'm not socially awkward in the sense that I get invited to parties but it feels weird when I try to approach women in clubs, house parties etc. etc. My lack of confidence seems play quite a large issue in this. I have a lot of fun at parties, but I would like to get to know females as easy as other people my age. When I talk to females, normally these situations occur:

1) I run out of things to talk about, even when the girl shows fair amount of interest.

2) I strike up a conversation, but don't know when to "touch them" or take it to the next level

3) They're not interested

4) Turns out the next morning, they tell someone else they were really interested in me, but I didn't pounce and ask for their number or tried to talk to them

I'm trying to make 2017 the year where I become more socially rounded than the previous years. I'm not sure how I should start, some people tell me that drugs and alcohol help with confidence but I only feel confident around people I know, but not with complete strangers/girls.
