I wrote and published a Quora answer (620 words). I saved as draft another one.
I created a giveaway post on my blog. It took me about an hour.
I shared the post in a few authors group on FB.
I wrote a broadcast for my InstaFreebie email list about the giveaway.
I created Amazon ad for my another book.
I optimalized existing ads and added some keywords to them. I did that with my son, who will soon replace me at this job.
I prepared everything in KDP dashboard for publishing Directed by Purpose.
I slept a bit over 5.5 hours. I napped 35 minutes on a train to work and 20 minutes on a train back home.
