Some of the practical advice I found noteworthy:
"Nothing can be always smooth, otherwise it's boring...You have to be tolerant to make [marriage] work..."
"It todays world you get a divorce if everything isn't comfy cozy. You have to be liberal with your love if you want it to last. Nothing is perfect. We struggled...but it was a very loving time, even though it was a tough time. You know the person so well. You know the good, the bad, and the in between..."
