Just to add, I think that many people (including myself to some degree, though I read most of those cynical "grad school survivor" books before I arrived my first year) really think that grad school is just an extension of undergrad. Would that it were so!

It makes you hate yourself, your subject, and all the people around you (including the cat). &*ck it. It's forced me to use the multi-emoticon lineup. :steam:
