Recently I had a female friend who's car became out of commission for a while. She was almost in tears saying how she was broke and didn't know how she was going to afford to get it fixed. So I gave her a ride back to her town about 10 miles away. Once we got into town. She said "Can we stop at the gas station. I want to buy some pop and stuff".
So her and her daughter went into the gas station. She bought 1 beer (because she was having a bad day) a energy drink, some pop and candy for her daughter. Total money spent $15. All on things they didn't need.
So that got me thinking, assuming she / you or someone you know makes this a very frequent occurrence, If you save $15 per day how much would you have in 20 years?
