It is not the absolute risk itself that is important, but what is behind the risk. It also matters how real the risk is. I usually use the analogy that if you have to walk through a minefield and you do not know the safe path, your risk is close to 100 percent. That is, the risk of dying is almost 100%. If you know the safe path through the minefield, then your risk is small. You can only die if you deviate from the safe route or forget it. This analogy emphasizes the importance of knowledge. It is very important to have good knowledge before you take significant risks. If your knowledge is exceptional, then the risk is essentially irrelevant - you will succeed. In this type of gambling, knowledge is a good strategy.
