What I would do when my priorities change quickly is I would stop and analyze the situation at hand. If an assignment was given to me by my superior that required my attention urgently, then I would pause what I was doing at the moment to prioritize their task to then continue with the work that I was assigned originally. An example of this would be my previous job that I was assigned my regular work, but a situation came up with my superior that needed to be handled at the moment. I proceeded to finish what was asked of me by my superior to then continue with my daily tasks.
