Ha, this is too true! The same can be said for the self-employed. The only reason I get up before noon now is because I'm self employed/a student.
Tess, I'm basically self employed too. Consider the last panel in the cartoon the struggle all creative folk have between "gigs" and staying up late the night before (because you could) working on some really crazy idea you wanted to make.
I hear that! I always feel quite accomplished if I can wake up before the PM.
Then again, I just stay up late when I can for reasons far less noble as being creative. If I only had a nickel for the times I've said to my self...OOOOO, (insert some movie here) is on!
