So

I used to play world of warcraft a lot. Compared to now, it was insanely lots. I came home, played until bedtime, went to work, repeat.

I eventually decided to cut down when I dropped dinner on the floor because my hand-eye coordination was lost. Tapping 2342342423 over and over != developing motor skills.

Now I only play for 3 evenings a week, and the weekends are always 'if I have time'. I'm even more successful than before, which goes to show that time invested doesn't correlate with positive results.
