A solid 4.5. I began following MC on insta in January. Her "tiny little joy" posts gave me something to smile about on some pretty rough days and added to them on the better ones. The whole "tlj" idea was not at all new to me as a long time Buddhist, but it was a new twist on the practice that enabled me to incorporate it into my daily routine, and I definitely noticed a difference in my mindset as a result. So when her book was released in the spring, I entered the goodreads giveaway (and somehow WON). As is usual for me, it took me a while to actually crack it open, but somehow I did so at just the right moment. In many ways, this was the book I was expecting ... this is not rainbow and platitude "joy" she's talking about... this is gritty, sometimes unwanted and obnoxious, sometimes a lifeline kind of real joy (mixed in with some wonderfully colorful and well placed f bombs, etc). Many of these lessons and practices meshed well with my Buddhist studies and practices, but I very much enjoyed the deeper dive into the science and the different perspective. Something I did NOT expect was the use of classic literature and philosophy as a way to illustrate or dive deeper into the concepts ... oh the JOY of my little liberal arts educated heart!!!
Something else I didn't expect was the memoir/autobiographical parts of the book. MC isn't just a therapist and research scientist (and clearly a big reader), she's BEEN THERE (and sometimes is STILL there). Like deep down in the pit of despair THERE. Her willingness to share that and be vulnerable to her readers definitely gave her words more weight and authenticity.
While it likely not all of the "joy thieves" that appear in this book are something I (and likely most others) can see in themselves, I still found these chapters interesting (and maybe found myself trying to diagnose loved ones ... lol).
The book is also full of concrete practices and tips, some of which work for me (like daily tlj practice) and others that don't really, but that's fine ... the spirit of the book is definitely "take from this what speaks to you".
I definitely would recommend this book to just about anyone ... even if you think you don't have a difficult relationship with joy, or haven't experienced great trauma ... you will still very likely get something significant from this book. I know I thought I had myself pegged as a victim of a specific type of joy thief, but through reading the entire book, I saw myself to varying degrees in several others and THAT was where I really learned a lot. I can't think of a single person in my life who wouldn't benefit from reading it.
