Although it's also awesome that I get paid for every minute I work, if the client wants overtime I get paid more, if they don't I'm out the door at 5. I set my own vacation allowance and when an email comes in from a client at 3am to tell us how awesome the product is I don't care.
So IMHO, go the other way start selling your time for a living. Stop pretending you give a crap about anything but yourself and cold, hard cash, go contract!
