I would also be enthusiastic about doing nothing in that heat! Awful!
A few of my non-fiction books definitely could use some reformatting and overhauling but I'm not bothered. I don't promote them; maybe someday I'll tidy them up!
But my novels have only ever had good reviews. By the time I publish them, I'm happy with them and haven't ever heard anyone say I should have done something differently.
Doesn't mean it won't ever happen but it hasn't happened yet! I'm a stickler for plot holes and details and things needing to make sense; I think this helps. Fiction has to be more believable than non-fiction!! 😆
Hope you can lay low and stay cool! 💜
