It is exhausting to read so many paragraphs about "success," when what they're really talking about is adherence to the capitalistic ideal. The quality of our lives and the value of our existence is not determined by what job we have, or how much money we make, especially when most of our labor benefits wealthy strangers. To have a happy family, meaningful relationships, healthy routines, and to know oneself: that is success.
Well... realistically the amount of money we have determines our ability to create an environment where all those things are possible. If you can find a way to become wealthy without sacrificing your sanity, and you know how to use that wealth well, then money makes the biggest impact on happiness of anything in existence.
