When I was freelancing, most of my projects were about 2-3 weeks in length. I had to find new work while trying to complete work. Difficult clients did not help that situation at all, nor intense deadlines. So truthfully, too much time would lapse between gigs, and running the numbers showed me that freelancing was earning around minimum wage, but I was working many more hours.

My best situation was when I had a client that was acting as a project manager and would feed me lots of work when I needed it.
