Should I just keep chasing pavements, even if it leads nowhere?

I'm quickly forgetting what it's like to have a life of any sort this semester.  On top the usual -- dissertation research, coursework, helping with grants, and the occasional lab project for another professor -- I'm now a graduate student instructor for an intro epid course with 200 students in it.  My weekdays seem to average about 12 hrs of work.  And my weekends are getting up there too.  I'm constantly exhausted and, somehow, constantly feel like I'm getting nothing done.

This weekend, I at least got the chance to run some errands in the middle of uploading and proofing lectures, working practice problems, and grading a gazillion homeworks.  I worked all day yesterday and a good chunk of today.  And, yahoo, I'm just right back in the mix of everything bright and early tomorrow morning.

This semester has made me realize more and more that I don't think I ever want to be a faculty member, as I think they might get less sleep than me.  Maybe... 




p.s.  My dog is crazy.  He just had a growling war with the couch while he was underneath it.
