Hi, Yes, it is true. If given the right opportunity I could keep writing and try to publish a novel regularly. But, as writing is still a hobby for me, it is not possible yet, Maybe in the future. :)
Don't be jealous, you are also a prolific writer and if given the right circumstances, you could also write and publish ebooks regularly.
It is human to feel a little jealous, I feel it too and sometimes wish I could be as prolific as the author James Patterson.

It is an honour for me to be able to share my work and my writings with writers like you and the other writers on Medium. Best Wishes from Warren
