During my eighty-seven years I have witnessed a whole succession of technological revolutions. But none of them has done away with the need for character in the individual or the ability to think.

Only as you do know yourself can your brain serve you as a sharp and efficient tool. Know your own failings, passions, and prejudices so you can separate them from what you see.

If you have made a mistake cut your losses as quickly as possible.

Whatever you do, do it with all your heart and soul.

Colleges don't teach economics properly. Unfortunately we learn little from the experience of the past. An economist must know, besides his subject, ethics, logic, philosophy, the humanities and sociology, in fact everything that is part of how we live and react to one another.

All economic movements, by their very nature, are motivated by crowd psychology.
