Investing is the intersection of economics and psychology. The analysis is actually the easy part. The economics, the valuation of the business isn't that hard. The psychology - how much do you buy, do you buy it at this price, do you wait for a lower price, what do you do when it looks like the world might end - those things are harder. Knowing whether you stand there, buy more, or whether something has legitimately gone wrong and you need to sell, those are harder things. That you learn with experience, by having the right psychological makeup.

Seth KlarmanSpeculators 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.
