Another valuable concept in poker is stack size. In poker, you should never play a hand in a game where you don't feel comfortable losing your entire stack. Similarly for running a company, you should try to make many small bets (or experiments) when the outcome is high variance. You shouldn't risk your company with every decision. Learning how to take lots of little risks well can even out the variance without ever putting you at significant risk.
