Confessions of a workaholic

Did you ever find yourself wanting to do more work but there is nothing on your plate? You are the kind of person who likes to be occupied at work but there is nothing substantial that requires your time and energy. I wonder how such people manage to spend minimum working hours in their offices. If the readers have any innovative ideas to fill up the idle office time, they are requested to post the same in their comments, because here is a person who is damn bored just because there is not enough work to keep him busy in his office hours. Seriously, it sucks big time when you just have to sit through the office hours without any work!! Or when you are so efficient that you always have plenty of free time very much during your office hours.. i think later is the case with me.. Anyways, are there any alternate money making opportunities that can be picked up leveraging the free time that you get in office? As i write this post, the clock has stuck 5.15PM and i decide to leave for the day..yes, probably two hours before my old colleagues here do...but i finished all the work allotted to me and i ran out of all options to pass free time in the office...
