My husband has been telling me this for years. Know your role. It is so true. When I take a moment and stop to really think about what my role in that situation is and what others think my role is, it often solves a lot of questions, even conflicts. We all have many roles. Some of mine are wife, mother, sister, daughter, artist, teacher, writer. Some of those mean different things in different settings. I have to tailor my role to the different expectations.
What do you really need to make important? What are others going to expect of you?
And those may not be the same things. Your attitude toward that role might make things easier. I know I need to remember this!
