As Sam says, PhDs are notoriously hard on mental health, and I think this is very not conducive to learning for most people.
For example, as someone who was a PhD student, I think I learned how to do these things:
“what to do when you’re stuck on a problem”, “how to use your network to effectively find solutions”, “when & how to ask for help”, “how to stay motivated even when you’re lost”, “how to lead meetings with your research mentors”, and “how to generally take care of your mental health”
only in the few months after leaving my PhD, though a lot of the learning was based on experiences in my PhD.
