This would be a great strategy for you and for anyone currently spending many hours creating content. Doubling up, multitasking is the way to go, like you are doing with the poetry book! Comedy club vlog would be cool. Not everyone wants to be on yt or video generally, but podcasts can be just as good, because many of us like to listen and not be glued to the screen.
There is a whole 'walkwithme' community here already too, out with their kids etc. Great post!
