I am exactly the same, I will start, then stop, then start again. Sometimes pause for days, it's so hard to keep a track of time. Not to mention that I might put together the render quickly (clothing, makeup, lights, setting etc) and then get stuck on a minor detail and spend hours trying to perfect that one silly item or find that one prop I absolutely need for the scene. I am a very nitpicky person so I am positive I spend way too much time on things that others probably don't even notice. The hours that I put on my last entries were just rough estimates, I am sure they are nowhere close to reality.
