Here's a thought and something to look forward to.
Everytime you go to the grocery store get a $20 back and put it in an empty water bottle at home. (so its not easy to get out). I'm sure we used to spend more but a $20 will do. Do this for 6 months or a year and you have yourself a little fun money. I'm going for a year and using it for vacation! Something to look forward to! Everytime I start feeling left out of a happy hour or drinks with co-workers, etc... I will think about going on a vaction
Maybe cheesy but I like the idea of having something to look forward to.
