I would also mention looking at what you do to satsify your natural inclinations.

I myself am very goal oriented. I always have to feel as if I'm moving forward on something. It took me years to realize what I enjoy most about games is the feeling of accomplishment you get from finishing them and I'm actively more productive in other areas of my life when I limit my game playing time. Not because I'm "wasting time", but because emotionally I'm not satisfied and find myself constantly working and building other things.
