The Confidence Gap by Russ Harris
I've read self-help so you don't have to.

Ah Russ Harris, sweetie pie Australian. He’s a practitioner of ACT therapy and has devoted his career to making it accessible to the public.
I recommend this book to all my clients, it’s like a jet pack for the work I do in sessions. Really, really helpful in developing mindfulness. His first book, THE HAPPINESS TRAP, gets into all of that if you’re curious. However, I mostly recommend this one:
THE CONFIDENCE GAP
An A+ self-help book. Straightforward, easy to grasp, and effective when you implement Harris’ recommendations. Highly recommend!
