In 100 years, much of the received knowledge of today will be proven to be wrong. Maybe even embarrassingly wrong.

One of the secrets of success in life is trying to discern which of the things “everybody knows is right” really isn’t right. And which things are.

Having placed your bets on what is correct and what isn’t, try to make your plans conform to those that will in the long run prove correct. And not confirm to those that in the long run will prove wrong.

Going against the grain can be a speculator’s friend. When people in large masses are running hard in one direction, betting against that direction often works. Use that knowledge to succeed and make money.
