Wow, I have been writing so long that I couldn't imagine not writing. I don't even know the answer to this question.
What would I do?
What could I do instead?
I can paint, and sculpt, so I have no doubt that I would still be involved in art in some way. I guess I would end up being around books in some way, perhaps working in a bookstore or helping others create books.
This is something I'll have to really think about, but, honestly, I don't want to think about it at the same time.
Let's watch videos of kittens playing instead.
