"Take a simple idea and take it seriously." - Charlie Munger The Rule of 72 is one of those crazy simple ideas that permanently changed my life for the better. And that is because twenty two years ago, I decided it was one of those core bedrock hacks! The Rule of 72 is a very quick (and surprisingly precise) method of figuring out how long it takes to double your money at various rates of return. I'll let the eloquent Professor Peter Rodriguez explain: https://www.youtube.com/watch?v=12FsjiVzTMA It does pay off (bigtime!) to know the Rule of 72. It is one of the most important tenets for us diehard compounders . Warren Buffett had probably mastered this rule before his 10th birthday. He knew he was going to be the richest person on the planet decades before he got there. He knew his rate of compounding, knew his life expectancy - and didn't need to know anything else. "Compounding is the 8th wonder of the world." - Einstein We, the compounders, agree with Einstein. It is all about the doubles. How long does it take to get a double and how many doubles can I get in a lifetime. And the Rule of 72 lets you do all the doubling math in seconds in your head.

Great day Mr. Pabrai. Any opportunity to consume your thoughts, ideas, and teachings is done so with eagerness. I was introduced to your work through Guy Spier's book "The Education of a Value Investor", immediaty read Dhandha investing, and then listened to Phil Town discuss how much he respected you. I'm so excited to have found your blog. Many thanks!

Dear Mr Pabrai.
Really enjoyed reading Dhandho Investor and instantly took to the concept of cloning. Your story has been an inspiration and this is year 7 into my journey and so far my sign reads COMLB14 :)
