Quick read that I heard about through Tim Ferris. A pretty quick read about hubris and how to avoid psychological mistakes in trading. Although we're not all futures traders it really doesn't matter, the psychology is valid for many financial situations like buying a house for instance. It also gives you some insight into how fast and loose some in banking/trading/finance really play it.
There is some minor trader technical jargon and the book drags towards the end when the summary is really to make a plan, stick to your plan and control your losses with the plan. Still worth reading considering it's short length and good message.
