Shrug, things you enjoy are good at getting you to do them often. But, WoW is just REALLY good at that. I've done a lot of stupid things, but when I played WoW it was just straight up addicting. Nowadays I really can't sit down and play it, I'm not sure why. I just can't get motivated to play, and thats a good thing. I played wow for a few months, not too long, and I had an unreal amount of days played. It's a hard habit to lose, just like smoking. It's funny how both turn out bad for your health though.
