I was recently asked to a group of potential PhD candidates about my own experiences during and after my PhD.
I think in many ways, my PhD was one of the more positive stories I have heard. I would do it again in a heartbeat (I often lament that it was too short). I had taken time off before starting and went back motivated and sure of what I wanted to get out of the process and where I wanted to end up. I had amazing supervisors, an engaging research project that connected with with inspiring supervisors and good funding. I had the tough job of choosing between a post-doc or a tenure track job both at amazing institutions.
