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

[PequDios]

So I am working most of the day. Not a hard work and lots of spare time for me. And I want to improve my poker game. Now I have read all my poker books (twice!) which are HoH V.I & II & III, Phil Gordond Little Green and Blue Book, Read 'em and Reap and The Theory of Poker. As I said I want to improve my game. I have the use of internet at work and lots of time. What should I do?
