So I am sitting here waiting for a progress bar to run (20 mins or so), and was wondering how best to use my time as a SysAdmin.

I debated not posting this question briefly, as this could get flagged as subjective, but I think it's an important question, and a question that can be legitimately answered (per the FAQ)

I know this something a lot of sys admins deal with, especially if they are client-based I would venture to guess. There is a lot of material out there about how to multi task, but SysAdmin work is unique in this area as well.

I could switch over to another project, but I could get wrapped up in that, and forget about the original project I was working on, and that's hard if you are billing a client for your time, both for tracking your time, as well as being fair to that client. I could check ServerFault, but that isn't directly work related, I could sort my email, so on and so forth.

What do you do, or what should I do when I have time waiting for a progress bar?

Thanks!
