How to spend my allowances

I have a plan to spend my allowances every week. My allowances every week is fifty dollars. First, I would spread my fifty dollars into two parts according to the weeks activities. Which would probably be ten to forty, or twenty to thirty. On part of it would be for spending on stuff and the other part would be for my savings.
