Nothing like a good trading proverb to lose money from.
“Sell in May and Go Away”
“The Trend is Your Friend”
“Buy the rumor, sell the news”
All classic. Not all accurate.
Charlie Munger, Berkshire Hathaway’s Vice-Chairman and the Tom Hagan to Warren Buffett’s Michael Corleone, had dozens of similar proverbs, parables and pithy aphorisms over the years. In fact, so many observations with his unique brand of dry humor and brutal honesty floated in the Wall Street air, he published a book with them all.
Yogi Berra played 18 seasons with the NY Yankees before retiring in 1963. He went on to coach both the New York Mets and New York Yankees for another 20 years ultimately having his Number retired (8) , joining the Baseball Hall of Fame (1972) and being part of the MLB All Century Team (1999).
He also had his “Yogi-isms” - impromptu pithy comments with an underlying humor and wisdom attached. His commentary and life philosophy also became so well known, appreciated and respected that he too published books to pass along the wisdom to future generations.

BFFs Yogi and Charlie
Honestly, these two guys are some of the best low-key American 20th century philosophers out there. Paging through their wits and wisdoms, it’s hard to ignore some of the commonalities in attitude and world view.
I love finding another voice who independently comes to the same conclusion as me - If both of these guys came to the same conclusion about an idea, despite entirely different life paths- then it’s worth considering adopting for yourself
Case in point:
Liquor, Ladies & Leverage
Munger: There is only three ways a smart person can go broke: liquor, ladies, and leverage
Yogi: “If the world were perfect, it wouldn’t be.”
Theme: Flawed behavior drives most human outcomes—not logic.
But the list goes on and on and on. A curated list of some of the more popular —-
