This book does have a good bit of helpful advice for those with ADHD struggling to organize their life and time. I appreciate the gentle and encouraging approach the authors took. It makes some good points but few I haven't heard before.

My one complaint about it was that there was a ton of tone shifting, making it difficult to focus on the content. (Which I already struggle with when reading nonfiction because of ADHD). It would continually flip-flop between conversational and clinical. My advice to those with ADHD who speed up audiobooks when listening to them is to slow this one down a bit from your typical listening speed. 

Overall if you have ADHD and find planning out your time to be a challenge, you may find this book helpful. If you don't have ADHD this isn't really the book to educate you about it. If you have looked up a lot of advice on the subject, you likely won't get much from reading it.
