Tips from readers, plus one of ours
- Read it for the man, then go to his own words. My Money Blog suggests Poor Charlie's Almanack first if you mainly want Munger's ideas, since this book is about his life.
- Know it stops in 2000. Per The Rational Walk, the only real complaint is that it's outdated, since Munger stayed active for more than twenty years after it came out.
- Pay attention to the hard chapters. Readers single out his early divorce and the loss of his young son, and his view that one tragedy shouldn't become two or three through giving up.
- Copy his poker lesson. He said playing poker taught him to fold early when the odds are against you and bet heavily when you have a real edge, because big edges don't come often.
- Arrange your money so you can stay in the game. One reader highlighted his warning that if you can't handle a stock dropping by half, you probably shouldn't own it.
- Our unusual tip: keep a fold list. Each time you pass on a deal, a purchase or a job, write one line on why. Check it a year later. You'll see whether your no's were good calls, which is the half of judgment people almost never review.
