Absolutely fantastic! congrats Joel - truly such amazing works, and glad you shared with us...albeit it, I'm late to seeing these posts; I typically read your most recent post.
I love to support my Medium friends and I will buy that last book. I have to admit that one concern I have is that Medium has pulled me away from reading books and I have to learn to create balance. Reading books is important and fun and I want that back in my life. I have bought three books from others and I'll definitely bookmark yours on Amazon as my wish list later this year.
Wishing you all the best - truly remarkable effort and work!
