You miss 100% of the shots you don't take!Tangentially, I hate this phrase. It ignores the fact that there's an opportunity cost to missed shots. If you're imagining the metaphor of a ball game, it's possession (and thus time and position). If you imagine the metaphor of a gun, it's your limited supply of bullets. This exhortation has an implicit assumption of endless resources, which are typically not available in the real world. Of course there are times you should risk things on an uncertain outcome, and be willing to move on to the next opportunity - trying to hold on to a declining situation is often motivated by a sunk-costs fallacy.
But I've heard the 'miss shots you don't take' thing proffered too many times as an excuse for ego-driven, risk-indifferent, and resource-wasting decisions and I'm pretty tired of it. There is a certain sort of person (but I don't men you, parent poster) who comes into a situation, fucks everything up, and then sails off with the excuse of what a bold, visionary risk-taker they are, blaming any obvious failures on the timidity of the team/colleagues. An excess reliance on sports metaphors has become a huge red flag for me in picking the people I work with.
