Have you ever written Guiding Principles?

Guiding principles are a set of statements about how we will act, based on what we believe.

Maybe you have them for an organization where you work or volunteer? Maybe you have some for your church or other group?

In my world, I also wrote 6 Guiding Principles for my team at work (written with my team at work), aligned to our corporate Guiding Principles, but adding more specifics based on the type of work my team must do.

I also have a personal document where I am writing and evolving my own Guiding Principles and Operating Procedures. (Operating Procedures work similarly, but are aimed at a more detailed level, helping to forge habits by having a pre-defined decision on how to act in particular situations.)

As part of my Monday morning weekly planning, I look over my Guiding Principles as a way of reminding myself what's important and how to act accordingly. 

Do you do anything like this?
Would it be valuable to share more about my principles?
