5.0

The most actionable, practical and resourceful self help book on the market.
This trumps all the 'inspiring and motivating' titles that crowd shelves by providing step by step, scientifically backed and practically proven processes to grow your willpower muscle.
It does not waste words at getting the reader to 'ignore their fears' or 'just do it'; instead it focuses on the cause of willpower deficit and seeks to create solutions accordingly.
Written in an immersive and clear-cut manner, it is a fast read even though it's a nonfiction. Though it is recommended to read it slowly over a course of months and try and implement each method to your struggles.
I would recommend keeping a companion journal to this book to avail the best outcome and take it slow instead of rushing through the book.
Simply, one of the best books I've ever read, this thing is life changing.
"When your mind is preoccupied, your impulses—not your long-term goals—will guide your choices"
