I love writing about Retrospectives. I would even say that it is my favourite Sprint Ceremony. Interestingly enough, my mood often depends on the outcome of the Retrospective, because I really want the team to improve.
So when the Retrospective is a success and the team finds great experiments to run in the next sprint and leaves the room in high spirits and lots of hope, I feel good, I feel I succeeded as a Scrum Master.
