Sara and I have thee notebooks. One is for her, one is for me, and one is for Emery. Instead of writing in these journals as personal diaries to ourselves, we use them to write affirmations to each other. It's like writing letters to each other but in a bound journal. Our daughter having been born yesterday, I just took the last 30 minutes and wrote a two page letter of affirmation and thankfulness to Sara. She will return the favor by writing me an affirmation of thankfulness as well. In addition, we will also write to Emery in her journal. How wonderful it will be for each of us to have all that love written down on paper for each of us to read in the years to come.
By the way, it is never too late to start.
