The standard self-improvement advice is to say No more often. That's frequently good advice. A lot of times we want to say No but are just too scared to do it. Sometimes other people are taking advantage of us. Or maybe we just neglect our own affairs to say No when we shouldn't.
But there's a case for saying Yes too. Yes has much more optionality than No. Saying yes to opportunities, even when they don't seem like they can amount to much, often has payoffs much bigger than we can imaging. Managing for positive optionality and opportunity is a key part of becoming antifragile and positioning ourselves to capture the upside from events.
