Coming out of my shell, any tips?

So, my past few years I have been very secluded, I seldom went to any parties, barely hung out with friends, never kissed a girl, you know, sad stuff. Missing out on my youth, but I wish to change. I have made one of my new years resolution to kiss a girl, but I don't know how. Not the kissing parti mean, but the act of actually finding the girl, talking to her, making her liek me, dating, whatever, until the kiss. I have benn given some advice by my friends, but what i need is a step by step thing. I know this maybe is asking too much of you, but if you could maybe condense this guide I am asking for into a few tips, that would be very helpful, and I would deeply apreciate it.
