My ownership over the projects I worked on has gone up enormously since I became a freelancer/contractor. I'm not here to merely put in the hours, I'm here to deliver the best product I can. And I tend to stay on a project until I'm sure I can leave without it collapsing.

My incentive is to make my client happy so they may hire me again, to get a successful project on my resume, and to be able to point future clients to this client if they want to know what I can do for them.
