For me, I feel rich when the money in my pocket can buy what I would desire. Since I am a simple man so even just $10 would make me feel rich. Now that I have lots of money in the bank my rule of thumb on wealth or being rich is the satisfaction. As long as I can satisfy myself with the material things that I can afford then I consider myself not only rich but a wealthy person. Whether I share my wealth or not it doesn't matter at all.
