I write about what matters...to you---
women, wives and moms---
about your family, faith and future.
I write about what's hard, what helps and what heals.
I show you how it's done. And not done.
I hold your hand as you find what matters to the Savior.
And let go of those things that mattered to you, but not to Him.
I write about what matters...to Him.

I’ve seen lists with lots more…but my rule is “use what you have, and take as little as possible” (since it won’t all fit anyway.)
But this gets us through and we’re prepared for anything that has come up.

What is an important need for you, may not be for me...adapt for your family's needs and comfort.
