Gambling & smoking limited but not entrepreneurship and stock trading?
asimjalis: I assume you are joking. Gambling is a closed system with fixed rules. The expected winnings form a Gaussian bell curve. Entrepreneurship is an open system. You can change the game. The idea of expected profits assumes that profits will follow a bell curve. But in fact they don't. There is really no upper bound. To use the terminology of Taleb's Black Swan, entrepreneurship profits are Mandelbrotian. The outliers can completely change the average, to a point where the concept of the average or expected becomes meaningless.
