The bit about having to overcome feelings of guilt about disappointing your advisor in order to live the right life for you really resonated with me. Taking the long-term view to make the right short-term life choices is something that many of my unhappy colleagues still toiling on their doctorates would benefit from. We PhD dropouts have decades of experience meeting and exceeding the expectations of others by the time we reach graduate school, so it feels like a radical step to finally place our own needs and desires above the need for validation from others in our lives.
