I always have been stuck with one thing. There were times when I was too deeply playing guitar, I would my guitar all day for countless hours. I was stuck in art at some point, I did nothing else than art. I was into programming at one time. And now since past two months I am stuck in online gaming a game called dota2. While into all of those above, my full priority was in those activities only. I ignore social events, friends etc while doing that. Is it some kind of disorder? How do I tackle this?
