Tired. So Tired.

I feel like I could sleep for days.... well, maybe just one. But still, the entire day.

Part of me can't wait until summer when the only thing I will have to do is research. The other part of me can't help thinking that if I'm tired now, only teaching one class, how in the world am I going to make it as a full-time faculty member? Having multiple classes to teach and hopefully a lab to run.

I love what I do, but where do you draw the line? When do you just say, enough is enough and for your own sanity lessen the load a little.
