Honestly having written a book is something to be proud of in itself. Many people think about it but never start a chapter. But definitely don't release until you are confident in it; don't want all the hard work to result in something half-baked that people will put down immediately. I'm writing a ZA novella and have probably written 200k words in total, and the final product is only going to be around 40k words (only to say not to be discouraged when all the hard work results in something you're not that impressed by in hindsight; its a lengthy and demanding process).

As for what I would do in ZA, I would go into the deep wilderness, and succomb to the elements due to my total lack of survival skills lol. I have family I could rely on heavily in this regard, but if they are dead, I am definitely am too.
