"Although the cheetah is the fastest animal in the world and can catch any animal on the plains, it will wait until it is absolutely sure it can catch its prey. It may hid in the bush for a week, waiting just the right moment. It will wait for a baby antelope, and not just any baby antelope, preferably on that is sick and lame. Only then, when there is no chance it can lose its prey, does it attack. That, to me, is the epitome of a trading professional"
