Nothing is a sure thing. Life in the present is hard ’cause you never know what’s going to happen next. You can make predictions and act based on data and evidence we’ve collected, and live in almost-certainty, but that’s the best we will ever be able to do. The question is do we gamble on the uncertainty or stick with safe-bets; do we risk it all on the big payoff or do we shield ourselves from the pain of loss and of failure. What algorithm do I follow?
