This idea of Roth's is so intriguing! I've been pondering it for awhile. Even to list the historical events of just your childhood could result in some seriously interesting writing. I'd really like to give it a try, but I actually never need to brainstorm for new things to write about because I can't seem to finish writing about the ideas that come to me naturally. It kind of surprised me that anyone would have to work that hard to come up with subjects, but obviously it sure is working out well for him.
