I am at work, nothing to do... what can I do to improve?

There are many things you can do depending on what type of player you are.

are you lag, tag, weak/tight, loose/passive?
what games do you play: nlhe, lhe, plo, lo8, 7cs?
what limits: .25/.5, 1/2, 5/10, 50/100?
what are the things you think you do best and what do you think you do worst?
