            | “To save money in college, I decided to do the   no new clothes challenge last year. This meant I didn’t buy new clothes for   an entire year. It was a little embarrassing to rewear the same clothes to   different parties and events, but it was worth it. After all, I saved all the   money!” ---Eden from   Mint Notion | 
        
            | “I copied a whole textbook. I didn’t feel like   buying a new one, so instead, I borrowed one from a classmate and copied the   entire thing using the copy machine. It may or may not have taken a few hours   but I saved $ 20. And for a college student who was broke, that was a lot!” ---Athena from   Money Smart Latina | 
        
            | “Cat litter(猫砂)is   something that can set me back a couple hundred dollars every day. However,   by toilet-training my cat with a $ 20 toilet trainer, I’m able to save on the   costs and avoid the trouble to change it. Plus it’s always funny to see the   cat on the toilet.” ---Dustyn from   Dime Will Tell |
