Several years ago I cam across a magazine article that asked if it was possible to put $2 a day away. I thought about it and decided to combine it with the idea of paying myself first. Each week I would take $14 out of my weekly cash and put it in an envelope and date it. Soon I realized that I had more than enough to raise it to $3 a day and I have been stashing $21 a week aside ever since. Each time I get $500 I seal it up and put it away.
I have been doing this for close to 5 years now. It is a habit. I have a minimum amount that I keep as an emergency fund and otherwise it is for the unexpected or single occurance things. I bought my son's HS ring from it, 4 new tires came from it and flowers for a funeral.
It is great comfort knowing that I have some cash on hand for when something happens.
