It's nice seeing people suggesting abt being mindfulness. Although I didn't read this book, but I understand what you mean here. Nice recomm.

Since we are talking about this, just a little reminder for interested ppl, it's more important to practice meditation than only reading any book on mindfulness.

Meditation is mental training. Understand it by practising meditation. Also for us to note is that negative thoughts are a defilement of our mind, abandon it :)
