Getting a mind map started

I'm stealing today's tip from Brian Johnson of Brian has some good advice on getting started with a mind map:
Take out a blank piece of paper. Write your question/challenge in the middle. Draw a circle around it. Now, think about ideas related to that challenge. Draw “spokes” out of the center—each with one idea on it and let your ideas flow…

That advice resonates with me. I think that's how I normally find myself doing a mind map. In addition, Brian recommends Michael Gelb's How to Think like da Vinci. I can agree that the book is well worth the read.
