One Bottle A Day

So here is a little game I call my 'One Bottle A Day'. Use any kind of bottle (wine bottle, soda bottle, soap bottle) and limit yourself to use only the one bottle per day.

For instance I might limit my soda intake to one bottle or I may save and reuse (for Art ) at least one bottle or make sure to recycle at lease one bottle. I find this game is good for health, wealth and planetary happiness . What could you do with a 'One Bottle A Day' rule?
