I decided that the best decision was to let others decide for me. I reached out to a number of economics blogs, explained my situation and said:
If I fail at my goal, I will pay your blog, or the charity of your choice, $100.They can keep the money, give it away or burn it in a sacrificial bonfire. It is up to them.
Greg Mankiw has chosen that his $100, should I fail, go to the National Council of Economic Education.
I will post the full details of the contract once I hear back from the various economics bloggers.
