Lately I've been struggling with content. I've tried and tried and tried to find an artist that could design levels and art in the style & quality I hope for but to no avail. Since I have been so unsuccessful I have decided to do it all myself.

But here's the rub: when I sit down with a big sketch pad and try to design levels...
...time passes and not much else happens. I don't know if I'm suffering creative block or if my inexperience that makes the task subconciously daunting. Either way, I need some help. So my question to you (all) is:
How do you go about your level design?
Do you have any kind of systematic approach?
Do you have some strange, quasi-legal ritual to get in the Zone, like sacrificing a chicken naked under a half moon? (what is a strange idea. who ever heard of a chicken with pants.)
How do you tackle such a big and nebulous task and break it into smaller pieces?
Any and all ideas would be studied, analysed, dissected, deboned, saute'd, memorized, and then secretly hidden away in a bunker under graceland.
