Meet Warren Buffet, one of the richest guys in the world. Through his investment fund, Berkshire Hathaway, he has been able to generate billions of US dollars by investing in ventures that have a clear value proposition.

But did you know he’s also a great life coach? In a YouTube video that was sent to me by Eiso Vaandrager, Warren Buffet gives the electoral speech to a class of MBA graduates. In his speech, he tries to convince the MBA graduates of the importance of integrity, next to intelligence and energy.

He explains the importance of integrity by a very simple thought experiment. The experiment is so simple yet so true, that I’d love to share it with you. Check out this video, and do the experiment yourself!
