All sound really interesting. I personally enjoy shorter books (book 1 in my series is around 30k words while the rest are at or above 50k) so think that’ll make the process less daunting if you go that route. Maybe during the week you can devote 30 minutes to writing no matter the word count? Or maybe try to hammer out 500 words on Sat/Sun? Just some ideas as I know writing on the weekends are a pain in the ass (usually take a break on those days lol).
And the audiobook might be free under KU. Here’s a link: https://www.amazon.com/gp/aw/d/B09GWDFF6M/ref=tmm_aud_swatch_0?ie=UTF8&qid=&sr=
Again, polarizing reviews lol. Definitely one of my more extreme ones.
