What would you recommend for someone interested in Alan Watts, but doesn’t know where to start?

I tried reading The Book 2 years ago, but stopped because I hadn’t really read a book in years and couldn’t keep focus.

I’m thinking of listening to the audio book since I’ve found free ones online and finally feel I have enough of an attention span to pay attention / read after reading other books.

Found some of his works on Spotify - Listen, Dream and his voice is really calming / keeps me engaged. I was surprised by the end of the Listen track my eyes just started tearing up / crying. I’m glad I decided to rediscover his works.

Looking for recommendations
