I think you will never have a good definition, because if the answer is "what people want?" everybody want something different. For my personal example, I do not have a lot (but a lot is here subjective) of money, enough to buy what I want (but I am frugal) and this enough for me to not think about money and have freedom of mind to think about my family, my friends and my startup. No million dollars bank account, but wealthy of experience, family with kids and friends (oh, and a lot of books, I love them).
