I actually have not known many academics who didn't want to quit and walk away from academia for any number of reasons. And they were valid like yours are. Even my person kept threatening to walk away (and she loved the scholarship -but hated teaching even though she was a great teacher (not just love bias here - she got student award after student award and all of her graduate students got jobs -she had a 100% record with her grad students getting teaching jobs soon after graduation) and become a gardener (ugh- I don't like gardening).
