Playing less than 20% of hands has you playing only 1 or 2 tables at a time even though you have 8 open. Once your here for a bit you will learn about software and huds that makes it so much easier to play even 10-24 tables. But that's for another time and not someone in your position. I would spend a day or two reading everything you can in the BC stickies. and also the FTR threads post by rpm here
