One of the joys of being a contractor is the complete lack of shame at leaving at 5pm, and being happy when asked to work later (aka get more money).

As a salaried worker I was easily pulled into working late hours as it was the status quo. In essence when you are salaried, you are owned, and will be frequently asked to work late, work weekends, and work from home at night. As a contractor, you will still get asked, but only when the reward for the company is worth the cost. As a salaried worker, the only cost for the extra time is your happiness, which isn't worth as much to them as you think.

The best jobs are ones where there is no expectation of hours though. This is where you have a significant stake in the outcome, such as an early employee or as an independent project. Where you are no longer getting paid for your time, but only for results.
