Solution

Begin with the end in mind.  If you are going to have a conversation or confrontation with your difficult person about what the problem is, you had better enter this discussion with a solution in mind.

You will get nowhere if you just vent your frustrations.  You MUST have a solution in mind to the problem.  This does not ensure you will get your desired solution, however, just venting your frustration or anger is guaranteed to backfire.

As “The 7 Habits of Highly Effective People” teaches us, “Begin with the end in mind.”  Have your solution prepared. Know what you want and be able to clearly identify that to your difficult person.

Just saying “You are constantly interrupting me” is not a solution.  Asking them to stop interrupting you is a solution.
