Not crazy! But it might be a female thing - have we talked about Imposter Syndrome? It seems to women most, and I know I fit the description to a T.

You know, one of the things about school that is a definite advantage over work is the variety in the schedule. It's too bad that jobs won't let you change your focus every couple of months, or even do the high school style segmenting of the day. I think this is what makes a full work day so draining. Not that you can't adjust ... I did, eventually, and people like Ann even manage to be disgustingly productive. ;)
