The book is a good lovely read which gives you lot of positivity. No regrets living helps you to live a peaceful life with very limited amount of regrets. Whether you believe in science or god, there should be some belief system that can help you to stay non egoistic and not to envy. I loved the way each chapter explains about different parts of life and how we should lead a life to stay optimistic even during tough times. I felt the book too very useful and the language and way of writing was so lucid. The author has written things based on his personal experience and stories of his life and people around him. I am one, who believe in miracles and when came to read the stories of survival and right thing happening at the right time which saved the life, I felt they are blessed and the gratitude and prayers for others in needs was something I started agin after reading this book. I really thank author for sharing his stories and experience as a book which can benefit many.

This book kind of reminded me of listening to your elderly grandfather give you basic life advice, over a series of hundreds of hours of letting him ramble. There's good advice but it's mostly basic and involves a lot of stories. The seven keys are things like believe in something bigger than yourself, have a sense of wonder, and foster connection. It involves a lot of stories from his personal family history (his family was greatly affected by the Holocaust) and his work as a doctor. It's a sometimes interesting read, sometimes rather preachy, and pretty long.

I read a digital ARC of this book for review.
