Firstly, kudos for all you have learned, built, achieved as an independent developer!
I feel quite certain that in the future you will have ideas for other SaaS products, and build more.

Which raises the question: what happens to VideoToPage when it is no longer your 'favorite child'? E.g. development of new features slows down, or it gets sold to someone else (who then invalidates the Appsumo LTD subscriptions since they are not recurring revenue), etc.
