I overheard someone talking about this topic, and it triggered a flood of thoughts in my mind. Is wealth the same as success? If you are poor, does that mean you have failed at life? I think the answer to both questions is NO! Here is a graph of those metrics:
What the graph aims to show is that Wealth and success are orthogonal- i.e. they are statistically independent. That is my opinion/guess. One of the difficulties with this topic is that while it can be argued that wealth can be objectively measured (ignoring issues like the value of your health), success is probably a very subjective measure. The definitions I came across were "the accomplishment of an aim or purpose" and/or "the attainment of popularity or profit".
The talk I overheard was a religious one, and the argument was that success is practicing the virtues, while failure is wallowing in the vices. Even if you are not religious though, it is worth pausing to think about what you are trying to achieve with your life. Is it wealth? Or Success? (or Happiness or Health .... or....)
