There is an opinion that the more money you spend, the more you get in return, it is interesting to find out who really works in this direction. I spend enough money, but I have a fixed income, therefore I will not be able to get more. I don't have rich relatives, and I don't expect an inheritance either. I want to get rich, not to deny myself, but I have to save on everything. Who really faced big expenses and received even more? How does it work, maybe I don't understand the essence of it correctly?
