What can I do about my life being ****?

I'm in the same boat as you are, except I don't go to college nor do I play the guitar. I wake up, eat breakfast, play xbox 360 and on the computer majority of the time throughout my day, and then go to bed, and do that all over again. It's ok to sit at lunch by yourself. I would rather prefer eating by myself, so I can keep to my studies and eat my food without having anybody bother me. If you are wanting to find a girl, or have some girls as your friend. Just go up and talk to them. Easier said than done, but if you walk up to a girl having a lot of confidence and knowing what to talk about ( which shouldn't be too hard if you listen to what the girl is saying, because girls like to drop in key words every now an then to see if you will be able to pick up on them, to show you if they are interested in you or not ). Go to Google and type in "how to become a pick up artist" and click on the first link! I used that website to help build my confidence in being able to talk to women and to have the ability to approach them without fear of getting rejected. And if I do happen to get rejected, oh well. The more you get rejected, the more prone you are to handling rejection better and not having that feeling in the back of your brain saying "I'm not going to approach this girl, because I'm afraid I'll get rejected". Just be confident in yourself and let the chips fall into place.
