Dr. Crazy over at Reassigned Time 2.0 has a fine post up about life after tenure. It's really smart (as usual) and also gives a strong sense of some of the things people should know and look forward to (with longing or dread).
I think her points about feeling pressure to contribute to the community (rather than trying to establish oneself) and about feeling pulled by different demands so that she has less time/energy to work with and teach her own ideas/research are especially useful.
Recently, too, Dr. Virago over at Quod She 2.0 had a post about the difficulties of feeling like she was in a "mid-career rut."
Both of these posts really resonated with me.
I'd add to Dr. Crazy's post about being pulled by different demands that one of the biggest demands I feel is the work on department and university personnel committees and such. Those tasks seem to take up a huge amount of time, and while they can feel rewarding, they can also feel unrewarded, if that makes sense.
Now, back to our regularly scheduled grading.
