"The business schools reward difficult complex behavior more than simple behavior, but simple behavior is more effective."
- Warren Buffett
In 44 years of Wall Street experience and study, I have never seen dependable calculations made about common-stock values, or related investment policies, that went beyond simple arithmetic or the most elementary algebra. Whenever calculus is brought in, or higher algebra, you could take it as a warning signal that the operator was trying to substitute theory for experience, and usually also to give to speculation the deceptive guise of investment."
- Benjamin Graham
