My problem is I don't have a social identity.

You'd think that would be nice, but it's actually alienated me from various groups. I thought that by not committing myself to one circle, I'd have a better variety of friends. But the space between circles is scary and lonely.

On the one hand, I have geek/nerd interests like video games, anime, and science fiction. I like to dabble in these and sometimes talk about it with other geeks/nerds, but very often their conversations bore me to tears. Although they are usually the friendliest to me, I hate their awkwardness, maybe because it reminds me of myself years ago.

On the other hand, I like cars, soccer, snowboarding, and strength training, which are more aligned with "jocks." They are a blast to hang out with because they like to go out and DO shit, not sit at home and play Guitar Hero for the billionth time. However, I still carry geek vibes, so I'm not accepted into their social circle so easily. In fact, they tend to keep me at a distance.

So what do you think? Can someone really attain mobility between social circles? I don't want to commit myself to one group but it looks like I'm missing out on a lot of fun.

I'm in a similar situation.

I have geeky interest my 'jock' friends wouldn't have a clue about and other things that my 'geek' friends wouldn't know about either. This has made it hard to associate myself with a certain group.

In the end I became so depressed I left school and became a NEET(lack of a better word); that was a year ago. Recently I've come into contact with my geek friends and it seems they're trying to get me to come back to school. They've also been trying to get me out of the house every now and then. Although going to net cafes and playing MMOs isn't my idea of fun; I think it was a nice gesture and I think I'm on the road to being associated with a social group.
As for my jock friends I haven't seen them for a very long time and I don't really think they care if I come back or not.

Anyway, I haven't gone back yet but it sounds promising and I think I might officially become a geek.

Well why not try making your own "circle" ? maybe there are some of the "geeks" or "jocks" that actually have the same problem as you? If you just be yourself maybe they will see that they are like you? ^^

I don't know how it is in your country, but I'm in the UK and I know people who enjoy sports/weight training and also enjoy playing video games. Generally they aren't hardcore into games, but like the play football or other sport games, and GTA is always fun. Just be careful you don't class everyone who is into sports as being a jock, because some of the nicest people are ones who are physically very active - the problem is that they are hard to spot on first impressions. So you could try joining a group sport to get to know some active people. If you find that you don't feel any kind of friendship with those people you can just leave after a few weeks.

As for your geek friends, do you try to organise things for them to come along to that aren't MMO-orientated? Or organise anything? Try organising a group of geeks to go to an amusement park or go bowling or something like that. You may have to put in a lot of effort to get them to agree to come out, but if you can do it enough hopefully you can bring them out of their shells a bit

same here.
or maybe no, actually, now I hate both groups.
geeks are too geeky, jocks are too.. jocksy?
lately the world for me has been looking like everyone is an idiot, some way or another... :/
But I like my girlfriend, somehow she is always cool with everything..
