It's not productivity. It's not innovation. It's identity. If you've lived a life where holidays are a nuisance, where you've missed your favorite uncle's funeral and your children's childhoods, in a culture that conflates manly heroism with long hours, it's going to take more than a few regressions to convince you it wasn't really necessary, after all, for your work to devour you.

It is VERY hard to not interconnect what a person does with who a person is.

We are what we repeatedly do.
