I know exactly what you mean. For me I think it's a matter of having too much choice. Choices of software, models, props, techniques, whatever. Leads to a paralysis of analysis, or just leaping from one amazing new software package or model to another. As a Poser artist, I've noticed that some of the more polished galleries I've seen consist of an artist using the same figure, subject matter or technique multiple times. Some use the same approach for hundreds of renderings, learning their tools inside and out. 

I'm going to try simplifying my renders to a minimum of objects and reusing characters, props and scenery for multiple images. Hopefully that will allow me to spend more time learning the ins and outs of the software, content and figures I already own. I'm also avoiding the constant upgrades to Poser, PhotoShop etc. Most of these packages are so complex that I've barely scratched the surface of their capabilities. 

I wish you luck in your endeavors.
