Saving money is not that hard but it can be hard when you do not make much money then it looks like saving money doesn't really works out. But even when you cannot put much money on the side it is still smart to do that.
I think saving money is a difficult thing, if the store is a simple matter of course there are many people who become rich, because they are easier to keep their money and do not wasteful
It isn't that difficult anymore when it's needed. I think most of us went through these moments when we needed something but had no money on us - if you really want to, you can do it.
