“I’m not interested in anything that’s not sustainable. Friendships, investing, careers, podcasts, reading habits, exercise habits. If I can’t keep it going, I’m not interested in it.“

— Morgan Housel

Quotes from the Rule of St. Benedict, ch. 64:

Let him hate the faults, let him love the brethren. In the matter of correction let him act prudently and not too severely, lest while he desires to scrape off the rust too much the vessel be broken; and let him always keep an eye upon his own frailty and remember that the shaken reed must not be crushed.
... Let him so apportion all things that there be something to which the strong may aspire and something the weak may not shrink from.

This episode includes Warren Buffett’s Snickers Story, plus the following quote from Charlie Munger, Poor Charlie’s Almanac, ch 3:

“Charlie detests placer mining. Instead, he applies his ‘big ideas from the big disciplines’ to find the large, unrecognized nuggets of gold that sometimes lie in plain sight on the ground.”

Above all, he attempts to assess and understand competitive advantage in every respect—products, markets, trademarks, employees, distribution channels, societal trends, and so on—and the durability of that advantage. Charlie refers to a company’s competitive advantage as its moat: the virtual physical barrier it presents against incursions. Superior companies have deep moats that are continuously widened to provide enduring protection ... Munger and Buffett are laser-focused on this issue: Over their long business careers they have learned, sometimes painfully, that few businesses survive over multiple generations. Accordingly, they strive to identify and buy only those businesses with a good chance of beating these tough odds.
