I manage my money by using less money on trivial things. It's easy to spend money on small things because of the cheap price. I was also tolerant about spending little money on trivial things, but I found out that these kind of expanse can amount to pile in no time. For example, there's a popular Korean winter snack called 'Bungeoppang' and its tasty smell always intrigues me every time I see them in the road. Because it was very cheap snack it was my habit to buy it whenever I wanted with no caution. As it was repeated, I could feel the money was escaping from my wallet faster than before and I figure out it was because I was spending almost price of a one meal on this snack. Similar experiences happened to me frequently that I resolved to refrain from using money on minor things. I think this is one of the efficient ways to mange limited amount of money.
