Mission Statement

I'm sorry if I'm submitting my questions more than once, I've been having a hard time with my internet and it seems to be losing connection when I submit.

I'm struggling to make a family mission statement. I want it to be something that represents our family, but I'm getting perfectionistic about it. My daughter has poor working memory and doesn't retain/memorize well. I don't want it to be overly long or complex but I'm having a hard time simplifying. Any tips?
