a lesson I learned in Teams that work with tickets

We had a ticket planning meeting. And by going through the tickets I noticed I hadn't completed a jira story in a long time. I got caught up in finding new things that I wanted to implement as part of the same story. I learned that the story needed clearer boundaries and a clear definition of done. I learned that a product of a story could be another story with another goal and new ideas. I will try to have a clearer focus on the story at hand. If I find new ideas I want to implement I will put them in another story. Otherwise you can get lost in your ideas and will never finish a story. I think a saying is "stop starting and start finishing" Did you have similar expeciences?
