Having read The Power of Now, I would say that this is definitely the better book.
It was written after the Power of Now and Eckhart Tolle is less rambling and more concise about how to live in the present moment.
Powerful and compelling stuff ... if only I could put it into practice, life would be so much simpler and better.
The Power of Now, is the idea that if you remove time from your life, and focus on the now, you are much more likely to be content. If you focus on the present moment at all times, then you can accept it, change it or enjoy it ... to worry about things that happened in the past or may happen in the future is not a good way to spend your life. The book explains how to live in the now ... I have tried the technique and it works but needs practice. You start by doing it for a few seconds and then expand upon the number of seconds, minutes and hours that you live in the present moment.
I am a self help book junkie, having read at least a hundred of them ... I would say this is the one book that helped me feel better almost immediately. Honing the technique is another thing entirely ... I'm working on it.

I read this book because a friend recommended it and then bought it for me. Sadly this is the worst sort of New Age claptrap – and I write that as someone who has read many, very good self-help and spiritually-minded books. This book however is filled with discursive platitudes and unoriginal concepts.

I did finish the book but gave up any semblance of goodwill toward it when I read: (Question): "Is there any scientific evidence of this?" (Answer) "Try it out and you will be the evidence." That's the complete opposite of scientific evidence!

Infinitely better alternatives: "The Way of Life, According to Lao Tzu" (Witter Bynner, Translator); "10% Happier" Dan Harris; "Catching the Big Fish: Meditation, Consciousness, and Creativity" by David Lynch; even the book written by a man convicted of felony negligent homicide (don't throw out the baby with the bath water) "Harmonic Wealth: The Secret of Attracting the Life You Want" by James Arthur Ray (with Linda Sivertsen); and the most obvious point of reference, "Be Here Now" by Ram Dass.

Cartea asta e un exemplu bun de ce în mod normal nu citesc dezvoltare personală: aceeași idee repetată cu metafore diferite, dar fără sfaturi punctate despre cum poți să îmbunătățești/să schimbi ceva.

It wasn’t a total bs, dar nici nu am rămas cu prea multe, deci kinda useless.
