Hmm without a computer. I would probably have a better job by now and maybe a girlfriend again if I wasnt online so much because of my gaming, news surfing, and message board reading. Or I might be holed up in my room working on my backlog of games dating back to the snes, genesis days to current PS3 and XBOX 360 games =P
If you're blaming your lack of girlfriend on this you either have high standards or are just making excuses, there's no end of women who'd happily sit there eating Doritos and killing some shit in Diablo 3 with you. They don't look like the super models and trophy wives down at the gym, but if you want one of those chicks you might consider taking up weightlifting instead (I'm not implying that all gamer girls, or guys for that matter, are ugly, I'm simply stating that people who spend mad hours at the gym are more likely to take a deep interest in their physical appearance and thus odds of being abnormally attractive go way up).
I.E. if you want a girlfriend go get one. If you have a repulsive personality flaw, fix it, then go get one.
Actually I do have somewhat high standards and I'm definitely not repulsive looking, I'm somewhat good at flirting with very good looking women just bad at the execution of going about asking them out which is because I'm at work and have to be very careful. Gamergirls are great, however I don't meet too many of them, the last one I was friends with had no interest in me. As for gym weightlifting is not my thing at all, I don't want to look like some uber grotesque women with lots of muscles =P
I probably have a bit of a personality problem as i am very cynical of life. I've had a bad past relationship which probably accounts to it somewhat. The whole Doritos bit was funny, unfortunatly I can't have junk food like that anymore do to severe stomach acid problems I get from certain foods.
