Just avoid things like racing trains to the crossing, doing cocaine, etc. Develop good mental habits.

Anytime anybody offers you anything with a big commission and a 200-page prospectus, don't buy it. Occasionally, you'll be wrong if you adopt "Munger's Rule." However, over a lifetime, you'll be a long way ahead - and you will miss a lot of unhappy experiences.

Everyone caved, adopted loose [accounting] standards, and created exotic derivatives linked to theoretical models. As a result, all kinds of earnings, blessed by accountants, are not really being earned. When you reach for the money, it melts away. It was never there. It [accounting for derivatives] is just disgusting. It is a sewer, and if I'm right, there will be hell to pay in due course. All of you will have to prepare to deal with a blow-up of derivative books.

In investment management today, everybody wants not only to win, but to have a yearly outcome path that never diverges very much from a standard path except on the upside.
