I've selected 10 of those quotes that struck me as financial lessons. Few were meant as such -- these are broad aphorisms not meant to be confined to finance -- but all provide at least some lesson that can help make you a better investor. Enjoy.
1. Education makes the wise slightly wiser, but it makes the fool vastly more dangerous.
Bill Mann calls this "Harvard stupid." Harvard stupid, he says, "comes from thinking that you're smarter than everyone, without recognizing that you still might not be smart enough to control the evil your creations threaten to unleash."
2. To bankrupt a fool, give him information.
I haven't seen the study, but I'm willing to bet there's a perfect inverse relationship between investing results and time spent watching CNBC.
3. "Wealthy" is meaningless and has no robust absolute measure; use instead the subtractive measure "unwealth," that is, the difference, at any point in time, between what you have and what you would like to have.
Plenty of those making $30,000 have ample savings. Plenty of those making $1 million a year live paycheck-to-paycheck and are buried in debt. Wealth is completely relative. As Chris Rock says, "If Bill Gates woke up with Oprah's money; he'd jump out the window."
4. What I learned on my own I still remember.
They teach about financial risk in school. If you still remember those equations, you're either a finance professor or devoid of a life. Learning something because you experienced it is the most valuable form of education.
5. The calamity of the information age is that the toxicity of data increases much faster than its benefits.
As the blog The Reformed Broker put it: "The four most dangerous words in investing are 'It's the Lightning Round!'"
6 The suckerís trap is when you focus on what you know and what others donít know, rather than the reverse.
If you find a cheap stock and you can't explain why it's cheap, there's a good chance you're missing something that others see. To quote Buffett: "If you've been playing poker for half an hour and you still don't know who the patsy is, you're the patsy."
7. Knowledge is subtractive, not additive -- what we subtract (reduction by what does not work, what not to do), not what we add (what to do).
A young child once asked Charlie Munger what advice he could give to ensure success in life. "Don't do cocaine, don't race trains to the track, and avoid all AIDS situations," he replied. What he meant, I'll presume, is that what you don't do is just as important as what you do.
8. A prophet is not someone with special visions, just someone blind to most of what others see.
Same as above. You'll win by default if you simply avoid the mistakes others make. Those who made a fortune betting against housing didn't have special insider knowledge. They simply didn't believe that housing prices could go up forever.
9. The best test of whether someone is extremely stupid (or extremely wise) is whether financial and political news makes sense to him.
One of the biggest disservices the media cranks out are daily market roundups that begin, "Markets fell/rose today on news that Ö" followed by a random and usually meaningless data point. Markets go up. Markets go down. Get over it and stop trying to connect the dots.
10. What they call "risk" I call opportunity; but what they call "low risk" opportunity I call a sucker problem.
The past three years, explained in one line.
Of course there really is an 11: As long as the little o is around and hairy and pelosium are still there, all bets are off.
