This might sound twisted, but something that helped me take more time to myself was when a guy who was “the only one who could answer certain questions” with something like 30 years of experience in our field dropped dead of a heart attack at home. We figured out what we needed to figure out soon enough and his position wasn’t filled for a year because five or six of us took up the tasks he was in charge of… My point being, no one is irreplaceable. Disconnect when you’re not at work.
o1 preview is insane really, it even corrects you when you ask a question poorly, or rather, it talks around your mistakes.
