P.11 People do some crazy things with money. But no one is crazy. People born into different economies, experiencing different job markets, learn very different lessons. Everyone has their own unique experience with how the world works. The person who grew up when inflation was high experienced something the person who grew up with stable prices never had to.

P.208 If you want to do better as an investor, the single most powerful thing you can do is increase your time horizon. Time is the most powerful force in investing. It makes little things grow big and big mistakes fade away. It can't neutralize luck and risk, but it pushes results closer towards what people deserve. Become OK with a lot of things going wrong. You can be wrong half the time and still make a fortune, because a small minority of things account for the majority of outcomes.

P.207 Go out of your way to find humility when things are going right and forgiveness/compassion when they go wrong. Because it's never as good or as bad as it looks. The world is big and complex. Luck and risk are both real and hard to identify…Respect the power of luck and risk and you'll have a better chance of focusing on things you can actually control.

P.168 It is a notion that assets have one rational price in a world where investors have different goals and time horizons. Example: Bubbles. Cisco stock rose 300% in 1999 to $60 per share. If you are a long-turn investor, 60 was the only available price to buy. What you don’t realise is that the traders who were setting the marginal price of the stock were playing a different game than you were. Sixty dollars a share was a reasonable price for the traders, because they planned on selling before the end of the day…

P.169 When investors have different goals and time horizons - and they do in every asset class - prices look ridiculous to one person can make sense to another, because the factors those investors pay attention to are different. Are you day trader? Then the smart price to pay is “who cares”? because you trying to squeeze a few bucks out of whatever happens between now and lunchtime…
