I've been saying for years that the job of a DBA is to make his own work as boring as possible.

I use SSC to stay sharp and interested.

There are issues that come up once in a DBA's career, if at all. By helping others solve them, I set myself up so that, if they come up for me, I'm ready for them, instead of being in the position of "I read about that once ten years ago". Instead, I'm in the position of, "I helped someone solve that last week, and a different person last month, and someone else the month before that, so I know exactly what needs to be done". That practice keeps me interested, keeps rarely-used skills sharp for the time I may need them, and makes otherwise boring days go by quickly.

My job is to keep my work as boring as possible. That doesn't mean the day is boring, it means the servers aren't doing anything "interesting" most of the time. That's a good thing.
