Did your system getting better the more money you spent or more experience you gained?

This is something that wanted to ask folks. Initially I said I would never spend x amount of dollars in this audio journey. 20 years later I’m here and did what I said I wouldn’t but I’m happier than ever. Best system to this date. But it wasn’t about money only. I gained knowledge on what was possible and the quality and design of the gear I wanted. I see people just throw money into audio and never be happy or satisfied. I think that happens because they don’t think for themselves as well as have the resources? Thoughts ?
