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.
It wont be possible to save anything if you are already earning what you need to spend on your family every month, in that case you will need not to store anything from your earnings otherwise you will be in trouble, but you can only start saving when you know you are earning more than what you need each month for general spendings.
