No matter how small, every experience has something to contribute.
So good to see you back in the writer’s saddle (though it was also good to know that you took time away from your craft to restore and refresh yourself).
Kudos to you for submitting a book prospectus, or a pre-prospectus. And perhaps even bigger kudos for appreciating yourself for making the effort despite not being from the publisher’s target groups.
I love it, and oh so true.
