The book The Responsibility Virus helped me a lot with this. Most people are over-responsible for the choices of others, specifically ones they can’t reasonably influence, anyway.

I stopped giving a shit a long time ago. I do my best to consult and warn and if they don’t listen it’s not my problem.

Took me a lot of years to not think it’s my company that is being run into the ground. I should not - and nowadays could not - care any less.
