“Risk is the ultimate differentiator. I have always had a deep and complex relationship with it. I am not a reckless person, but taking risks is really the only way to consistently achieve above-average returns—in life as well as in investments. My father proved that when he left Poland. I am probably more comfortable with risk than most people. That’s because I do as much as I can to understand it. To me, risk-taking rests on the ability to see all the variables and then identify the ones that will make or break you.”
