“One of the errors people make in business 一 and sometimes it can be a huge error - is that they try and measure every deal against the best deal that they've ever made. So they say, I made this wonderful deal for, maybe, an insurance policy written, or it might be a company bought, it might be a stock bought, and they're determined that they're never going to make a deal that isn't that attractive in the future.
So they, in effect - sometimes they take themselves out of the game.
The goal is not to make a better deal than you've ever made before. The goal is to make a satisfactory deal that's the best deal you can make at the time.”
-Warren Buffett(2011)
