There are a lot of things you can do to increase your joy without money. Monetary wealth is a beautiful thing but it usually starts from the inside out, but if your mentally and emotionally unstable, have poor relationships, or suffer some physical ailment, for example, then money isn't the answer. Having personal prosperity means that you should not sacrifice the other important areas of your life in the pursuit of earning money because it will consume you. Having money is obviously important but it shouldn't be the only criteria for real success.
