Almost no one will accept responsibility for his or her role in precipitating a crisis: not leveraged speculators, not willfully blind leaders of financial institutions, and certainly not regulators, government officials, ratings agencies or politicians.

Investors should always keep in mind that the most important metric is not the returns achieved but the returns weighed against the risks incurred. Ultimately, nothing should be more important to investors than the ability to sleep soundly at night.

Rather, risk is a perception in each investor's mind that results from analysis of the probability and amount of potential loss from an investment. If an exploratory oil well proves to be a dry hole, it is called risky. If a bond defaults or a stock plunges in price, they are called risky. But if the well is a gusher, the bond matures on schedule, and the stock rallies strongly, can we say they weren't risky when the investment after it is concluded than was known when it was made.

Warren Buffett is right when he says you should invest as if the market is going to be closed for the next five years. The fundamental principles of value investing, if they make sense to you, can allow you to survive and prosper when everyone else is rudderless. We have a proven map with which to navigate. It sounds kind of crazy, but in times of turmoil in the market. I’ve felt a sort of serenity in knowing that if I’ve checked and rechecked my work, one plus one still equals two regardless of where a stock trades right after I buy it.

The way to maximize outcome is to focus on the process.

I think Buffett is a better investor than me because he has a better eye toward what makes a great business. And when I find a great business I'm happy to buy it and hold it. Most businesses don't look so great to me.

Ultimately, nothing should be more important to investors than the ability to sleep soundly at night.
