Thanks for responding, everyone.

This has been a lot to digest, but I've given what you all have written some thought. Unfortunately, I don't think game design lends itself all that well to some of the methods requiring rapid creation as practice...At the same time, there are certain elements creative practices do share.

For one, having the discipline to work through the more tedious segments of a creative process is critical. On that note, I think figuring out a creative process should be my next step, and that will require experimentation, I suppose.
