Brilliant! These are all so simple and practical but most people never get around to building these habits. I've personally found each of these questions very helpful in strengthening my relationship with my partner.
Another question that could be included in this list is - "what can we do to be a tiny bit happier in the present?"
Endlessly talking about the future is a pitfall I've personally faced, and this question has helped me appreciate the relationship for what it is today.
