You know when human civilizations were naive, people used to use barter system to trade across with each other. That system became complex and difficult to manage over the time and hence came the concept of money in picture.
Money was actually devised to make spending easier. In fact, as per its origin, it is valuable only if you can trade it for some stuff or service you need. But as per my view it is valuable even if you save it and not spend it. Saving the money will give you peace of mind that if some emergency strikes, you can tackle it relatively peacefully.
Funny isn't it?
