The most valuable thing money buys you is first security, directly followed by freedom. I would never trade that freedom in for some shiny toy, or trinket. Or something to impress other people with. If it is something I truely enjoy, and can afford comfortably sure. But then is much more about the experience than it is about the thing.

And if people judge you as person based on the car you have, the clothes you wear or the appartment / house you live in, well, maybe ignoring those people actually is a healthy thing to do.
