In July 2016, Bill Gates wrote a memoir on his 25 years of friendship with Warren Buffett. Here is how Gates started his memoir –
I don’t remember the exact day I first met most of my friends, but with Warren Buffett I do. It was 25 years ago today: July 5, 1991.
I think the date stands out in my mind so clearly because it marked the beginning of a new and unexpected friendship for Melinda and me—one that has changed our lives for the better in every imaginable way.
Warren has helped us do two things that are impossible to overdo in one lifetime: learn more and laugh more.
That last note caught my attention. Including the two lessons that Gates learned from Warren, there are four most important lessons I have learned from studying the latter and his partner Charlie Munger over the past 15+ years.
