This book changed everything for me, I was going through a very difficult time in my life and this booked pulled me out of the depths of hell. I listened to the audiobook which was amazing, I must of listened to it 7 times in 4 days and it is now my go to book when I feel the stress of life getting to me again. Logically and spiritually excellent. I apply the 4 agreements in everything I do now and I feel alive.
