7 day challenge

I am wanting to go 7 days without spending a penny. I started tracking all my expenses since this past August and noticed there really are not many days I don't spend a dime. I may go a day or two without buying something but nothing more than three. I want to challenge myself to 7 DAYS without spending anything. I am starting today, October 17th. I will get back with you guys on Oct 25th. Wish me luck!
