In the monetary sense, I'm far from "wealthy" by most people's definition... or even by my own definition of the wealth I would like to attain. I feel wealthy though. I have just about every material item I feel I could possibly want at age 25 without any debt aside from my mortgage. I'm enjoying my work and my financial future looks bright so I have that to look forward to.
It's really easy to get so caught up in what you want, or what others have relative to you... that you neglect to take the time to enjoy what you have right now. Pretty much everyone on this forum drives a brand new BMW so you should at least be able to take some pleasure in that.
Money doesn't buy hapiness, but setting goals and challenges for yourself (whatever they are) and reaching them is a very satisfying feeling. I have plenty of them to look forward to, I hope.
