If having money isn't 90% of what being successful is all about. please tell me what is.
You are mistaking cause and effect. Having money doesn't make you successful, but being successful often results in earning money, as a mere consequence. Thinking that money in and of itself makes you successfull seems very primitive and materialistic. Some of the most detestable slugs in this world are obscenely wealthy, yet seem truly miserable, and are not successful by any standard of mine.
