I once read that someone had quantified happiness at being 10 million dollars based on the total cost of "freedom" from debt, owning the house of your dreams mortgage free, cars, money in the bank to live stress free the rest of your life, etc.
So, you only really need 10 million to be happy in life. Anything more than that is excessive. Therefore, I would take the 10 mil and already be set for life. I wouldn't need to learn anything else from anyone as my need for money would be met already.
And, like @angelo
said, both of those men had just copied someone else's ideas. Much like Trump's money, it's easy to make when someone else is already handing you the keys.
