I think that the same actually goes for managing money or investing/gambling. Once you learn to lose, get used to watching shit go wrong, you just stop "caring". Ofc, you still care, it's just that shit happening (financially) no longer messes with your emotions.
I've recently had a lot of losses and bad news, and the only thing I can say I'm feeling is apathy. Guess it's a defense mechanism.
in a way it is yes.
