Sometimes we forge our own principles and sometimes we accept others' principles, or holistic packages of principles, such as religion and legal systems. While it isn't necessarily a bad thing to use others' principles - it's difficult to come up with your own, and often much wisdom has gone into those already created - adopting pre-packaged principles without much thought exposes you to the risk of inconsistency with your true values.

The biggest mistake investors make is to believe that what happened in the recent past is likely to persist. They assume that something that was a good investment in the recent past is still a good investment. Typically, high past returns simply imply that an asset has become more expensive and is a poorer, not better, investment.

If it didn't happen in your life before, then you're not paying attention you don't think it's possible. But almost all important events never happen in your life before.

I believe that our society's "mistake-phobia" is crippling, a problem that begins in most elementary schools, where we learn to learn what we are taught rather than to form our own goals and to figure out how to achieve them. We are fed with facts and tested and those who make the fewest mistakes are considered to be the smart ones, so we learn that it is embarrassing to not know and to make mistakes. Our education system spends virtually no time on how to learn from mistakes, yet this is critical to real learning.

Once you accept that playing the game will be uncomfortable, and you do it for a while, it will become much easier (like it does when getting fit). When you excel at it, you will find your ability to get what you want thrilling.
