There are no long-term lessons - ever.

You need humility to say 'I might be wrong.'

Be focused on process and not outcome

The risk of an investment is described by both the probability and the potential amount of loss. The risk of an investment-the probability of an adverse outcome-is partly inherent in its very nature. A dollar spent on biotechnology research is a riskier investment than a dollar used to purchase utility equipment. The former has both a greater probability of loss and a greater percentage of the investment at stake.

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.

In a crisis, stocks of financial companies are great investments, because the tide is bound to turn. Massive losses on bad loans and soured investments are irrelevant to value; improving trends and future prospects are what matter, regardless of whether profits will have to be used to cover loan losses and equity shortfalls for years to come.

Speculators are obsessed with predicting: guessing the direction of stock prices. Every morning on cable television, every afternoon on the stock market report, every weekend in Barron's, every week in dozens of market newsletters, and whenever business people get together. In reality, no one knows what the market will do; trying to predict it is a waste of time, and investing based upon that prediction is a purely speculative undertaking.
