I've been going to the gym for almost 4 years now, from 1-5 times a week (depending on what else is going on). The times that would interfere most are when I have a girlfriend b/c they tell me I don't need to go, I should hang out with them, etc etc. But I would still find a way to balance it out. I could never pull myself away from the gym b/c it makes me feel so much better, and I'm in great shape b/c of it. I would spend lots of time hanging out with friends, cooked dinner every night (I was well known for cooking healthy food that tasted good...ppl tell me to join a culinary school), washed my car alot and hung out with a car club (I'm obssessed with cars and spend half the money I make on mine..heh), and I would watch almost every movie that came out.
Thennnnn...my stepbrother drug me into FFXI. I was not going to play this game b/c I knew I didn't have the time for an online game. I remember reading articles about people playing them, getting addicted, and blowing off their entire life just to play....that seemed nuts and I wanted nothing to do with that. But me being a big fan of past Final Fantasy's I thought I would check it out. I went and watched him play at his house, and I got hooked. I went and bought it the next day. I started going to the gym ALOT less, stopped talking to my car club buddies, stopped going out with friends on the weekend, stopped watching movies, and just sat and played and played and played. I get so much shit for playing this from so many people it's sickening. After a while people just pretty much gave up on me. Getting me to quit was hopeless. I realized this was a problem and tried to quit playing...and like most others I found myself back into the game within a week.
My goal for this year is to try and focus more on irl, and play FFXI alot less. I still have alot of rl friends and hobbies that are all here...and I want to spend more time with them. I got some new running shoes and an IPOD for christmas, which motivated me to start going to the gym more (I have still been going just not trying as hard...almost like I don't care). I also wnat to start cooking more (maybe go to that culinary school here I've been eyeballing), and going out with friends on the weekends instead of having 12 hour FF sessions. We will see how it goes

Sorry for the long post.
EDIT:
Sorry I mentioned FFXI...it has to do with my goal...heh.
