I speed up my production time by working on 2 or 3 things at once, believe it or not. I notice that I slow down when I start to get bored with mundane things like post working 400+ frames of an animation. So I open Wings and model something. When I get that done, I will work on something in Sculptris or start a new scene in Poser. Then go back to the mundane post work. Things get done. And I don't get lethargic and stop all together for any length of time.

Try something you haven't done before. The challenge of learning sparks the creative juices in me and usually prompts me to finish something. And I move quickly because I am excited for the results. Just don't let this cause you to cut corners...

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
