    That "blow out your headphones" music is back.... Thanks, RVTV. The people in the coffee shop missed me screaming and throwing down my iPad and ripping out my EarPods in a painful outburst - arrgghhh!

    When you combine the MACHINE LEARNING REVOLUTION interview and the FIVE BEHAVIORAL MISTAKES INVESTORS MAKE interview, you see how powerful Dr. Villani’s machines are. I believe it is the combination of machine learning with market acumen that will provide the edge. Just like having a pilot in the plane when it is on autopilot, it is the combination that will work. Very few people will have both of those skill sets. DLS

    It's sobering (being a macro gadfly myself) to hear another investing legend in addition to Buffett say macro is generally beyond their abilities. One of the points made in Superforecasting by Tetlock which expands on many of Michael's points is the primary importance of choosing the most predictable problems on which to focus your forecasting energies. Obviously Michael and Warren have decided that starting point should be narrowed down to bets on companies with a 10yr track record of stable and high ROE, entered with a margin of safety, without leverage, as part of a portfolio, held through drawdowns as long as the thesis is intact, and perhaps reweighted when over valued.

    I'd say if you take most people, their real issue is being too risk averse than being too gung ho and risk taking. I recently went round asking just about everyone I know: "If I offer you a 10/1 payout on a coin flip, how much over your net worth would you bet?" And very few people replied any kind of acceptable amount, many people even said "Nothing, I don't gamble." I found the whole thing rather depressing, evidence that I need to surround myself with better people.

    Over the course of a life, a career, you need to actually play a hand. Just make sure you're still standing to play the next one too.

    This is gold. We all need a concrete process to help us mitigate these problems. Journaling is a great start.
