"Certainty" Is An Incomprehensible Word To A Rational Investor

I am not certain about anything. "Certainty" is an incomprehensible word to any rational and responsible investor. Only political ideologues, religious fanatics, and other madmen believe they have all the answers. Happily, you need neither omniscience nor certainty to get rich. All you have to do is pay attention to where the opportunities are in the markets, keep an eye out for major changes that might affect them, and then act rationally and responsibly.
