Love this quote; few people in the industry talk about using stress testing. You don't hear about it much. There is only one relevant book on the subject, and it's geared toward banks.😴😴🫩

Stress testing enables you to look at how all of your different investments may perform in a shock... In addition, you can turn stress testing on its head and turn it into a forecasting tool, looking at times in the past where we’ve seen bouts of inflation and how the different asset classes have performed, and you can actually perform some forward-looking calculations about how your current portfolio may perform.

In regards to Charlie Munger's quote... A young man came to him, and he said, “I want to compose symphonies. I want to talk to you about that.” And Mozart said, “How old are you?” And the man said, “Twenty-two.” And Mozart said, “You’re too young to do symphonies.” And the guy says, “But you were writing symphonies when you were ten years old.” He says, “Yes, but I wasn’t running around asking other people how to do it.”

Munger is implying that Mozart was somehow magically a prodigy. When in fact he wasn't, and neither was Warren. Mozart's father was a violinist, and so Mozart himself became obsessed with music, or it was forced onto him through repetition. Regardless, he was exposed early, and so he began early. It also implies that there is something wrong with cloning or seeking shortcuts from individuals who already have an answer. Warren has been a clone his entire life; it began with Ben Graham, moved on to Royal Little when he built Berkshire, and ended with Philip Fisher. Warren and Charlie may have gotten answers from books, but they got the answers from others no less. Almost all of life is repetition day in and day out, same actions producing the same results. And to raise them up as if they are somehow prodigies is ridiculous. They were just born at the right time, to the right people, with the right interest.
