How does one measure wealth

I plan, I budget and I save up in the correct ways. I haven’t lived with my parents in 6 years, I have an average paying job, and I live an average life.

But my car/autocrossing is THE most enjoyable hobby in my life, and as such I make sacrifices to be able to afford it. I’m not talking sacrifices like I don’t save any money or just put everything on credit cards, that’s far from the truth. I budget properly so that I can afford my hobby, and I avoid things like shopping sprees, or expensive gadgets like a Wii or iPhone. I just simply don’t need them.
