Welcome, Steve!
I'm sure having a creative mind helps, but I think that the main points for being good at LDing are:
- Constancy: think frequently about dreams and LDs, and do reality checks often, not as something mechanical, but really "questioning reality" (don't accept that you're awake until you prove it, even if you know that you're awake)
- Patience: you can have a LD pretty soon, or it can take you some time. Don't get discouraged if you don't succeed at the beginning, or if you have several LDs and then stop having them for some time. I'm having a dry spell myself that lasts for several months now but in January I had 3-4 LDs a week!

BTW this is my first post in several months, I've been really busy for some time, but it's over now This is another thing to remember: stress and concerns are the worst enemies of LDing.

See you and good luck!
