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?
There's a range of different scenarios where this might be true, there is an old theory that you should dress to impress and look the part when going for something like a new job. A suit can look way more professional and flattering than other people who might turn up in more casual clothes to interview. Then there is the idea that if you buy cheap, you end up buying twice, which needs some thorough thought. If you're putting together a tool box for example, you might buy cheap the first time and figure out what you're using so much that it breaks - then as you replace those items you can increase the quality because you tend to use it more regularly than other tools in there and it's important not to keep buying the same item that might break quicker.
