It is often said that the biggest difference between the rich and the poor has it origin from the mindset.
This is mostly said by the rich, they need to justify somehow that they are not rich by chance, by family or by the people they know so they say that they have special "supermindset" qualities that make them rich. Anyway, being honest, there is some truth on this. For example Elon, who I dislike particularly, could have settled with the money he made from the Paypal sale and he would have lived a nice life, he chose to do more.
What I am not certain is that being a business adrenaline junkie is a desirable trait, even if it makes you rich.
