I was given this book by the author to write a review.

I don't usually read book about productivity. My all time favorite remains Eat your frog and that would be it; I have created my own tricks and since they work pretty good for me, I have stop looking for more "hacks" to improve my productivity. However, I decided to read this book to see if I could get new tips and tricks to include in my life.

It turns out that "15 Secrets..." is a very good book. It is written in a very simple way and has tons of small pieces of advice. Too much I would say actually.
What I like the most are the places the author goes to get fresh feedback: Great students, Olympians, Entrepreneurs and Business people.

At the end I di not find new things; i did realize though I share the basic aspects to be productive:

- Be an early riser.
- Physical activity
- Healthy food
- Write everything down on your notepad
- Schedule on your calendar
- Delegate
- Take long walks to let your unconscious mind do the work (I'm just not a yoga person)

I think at the end, productivity is a very intimate process. You cannot fool yourself and in order to improve your output, you need to know your strengths and weaknesses.
This book reflects how others have done it; that might shed some light to your inner process but remember, is always whatever works best for you.
