I want to make money so I can help people. To be able to invest in things which might cure diseases, solve hunger, produce cleaner cheaper energy. Things which might have an opportunity to drive humanity forward.
I want to make money so that I can change the world. Not in the superficial way that people think you mean when you say that, but in real ways; in ways that create true value for humanity. Things that might drive us closer to a star-trek-esque free-energy economy.
This is what people don't understand about money. Some people want it because it has the power to do a lot of things. It is a measure of value, and you can use that value to create more value. It might spiral so high that you don't even know what to do with it anymore; and that's okay, because all it means is that you've produced value and created something real. If I have billions of dollars when I die, I won't care if I lose it. The real reward was the creation of which it was an accidental result.
Travel? Nice things? Acceptance? Popularity? You think that's why people want money? Child's play, all of them.
I noticed you have this on your first list: "create the biggest impact possible?"
But you never responded to it. It's because it's the real reason. Money is a means to create the biggest impact possible. It is a means to create. Full stop.
