Never, ever, ever print out a 360 page manuscript without checking to make sure you are printing out the CORRECT file.  Not just the right name…but the right file.  Since I some of us are sort of scattered and don’t always delete the old ones, I a writer can never assume they are printing out the right file.  Because that old one that should be deleted wasn’t in the right format, had some of writing notes in the MS, and is basically not something I a writer wants my an editor to see

Failure to do this wastes a lot of paper, time and is a huge headache.

Not that I know from experience or anything.
