My hands this year 2008. I am putting in 211,8/11 = 19.2h/week and am finding it really hard to motivate myself and have the discipline and energy to play much more. These 40-70h week estimations just blow my mind. unless you sacrifice other parts of your life almost completely. In addition to these hours you need to spend time studying and discussing the game to improve, how one can have time for that with such workload is beyond me.
