Is Yoshihabs preaching fatalism here? Is that what it’s come to? No. Not at all. He’s talking about timeboxing. Sometimes, you think and think and think and think and still can’t come to a decision. So what do you do? Well, if you’re smart and sensitive person, you curl up into a ball and fester in a state of permanent indecision that morphs into a multi-year bout of clinical depression. But if you’re even smarter and wiser than that, you cut your losses and make a decision anyhow. The GOAT of shogi does not waste his time overthinking. Which is not to say that he doesn’t think at all. He just doesn’t get lost in a thought quagmire. He doesn’t get embroiled in mental Vietnam/Afghanistan. He gets the heck out and moves the heck on.

Don’t overthink. Set a cut-off point. Let life go on (it will anyway, but you need to let it go on for yourself as well, innit). Make the game winnable, that is, make it finite; give it many internal end-points ¹ and “save-points”. Let there be an end to your fussin’, and let yourself be the one to decide that end: give yourself that authority.
