If given a chance to trade anything of the wealthiest people, what is the right thing to trade?

Their money? Status? Network? Hard work? Life Lessons?

The best thing to trade for is their curiosity.
What do they think about the most? What is the pattern of their thinking? What are their mental models?

Curiosity can make us figure out a way to make a motor car in a world where everyone wants a faster horse cart. 

Lack of it, can make us believe we are meant for slow commutes forever.

Having the wealth of the wealthy is like eating fish.
Having their curiosity is learning how to fish.
