It's something I'm thinking about at the moment. How little can I spend on my "entertainment" budget? I want to spend the absolute minimum possible. It will give me an excuse not to do some things that are bad for me, and save me some money. It's also a good exercise in acting intentionally, instead of following the same old patterns. I'm thinking as low as three buck a week. I've long been thinking about five, but three would be even more of a challenge.
