Just an observation. I think Elon is one man who is not motivated and driven by money.

One who's driven to make money for the sake of having money often ends up not being happy and often self destruct, because there's always more money to make.

And then there are those are driven to achieve a goal, other than money or possession. There aren't many such people around and it's especially refreshing to see someone who not only has such dreams (other than making money) but is achieving them.
