Do not analyze too much crap in a short period of time.
I went on my usual flagging spree for the week and after viewing 200 links and rapidly analyzing the reviews to see if they should be flagged or not my brain was fried. I have very little time to look through 300 links (like 40 minutes) of submissions to find abuse.
While analyzing a lot of data quickly will expand your mental capacity (which is extremely useful) it will also hurt a lot. So when reading stuff and judging it, take your sweet time or else you're going to regret it. I have a headache already.
Damnit.
