## Customer Reviews

### ⭐⭐⭐⭐⭐ Evidence-based Happiness Journal
*by M***A on May 24, 2019*

This is the second of Prof. Dr. Beeker's books that I have purchased & read. The last book I read was "Master Your Emotions." His books are credible in that they are backed up by research and his decades of experience.This journal is no exception. It is like the "Daily Bread" of happiness & de-stressing. It is an effortless daily journal to work go through.It is best to work through the journal every evening, consistently for 90 days. It only takes a few minutes to do the daily exercises in the journal.Each day kicks off with a high-impact quote. I loved the quotes & will print some of them out to reference in my other work. Then you work through 3 well-researched questions every evening that help you reflect on each day; look at the past, the present and imagine the future that you want for yourself.Prof Beeker has also thrown in a resource library where you can find other templates that are not in the book plus an address where you can contact him directly should you need more support.It is a tried and tested method that will lift your happiness index should you stick with it through with it for the 90-days.

### ⭐⭐⭐⭐⭐ A Wonderful book for pursuing what feels at times like the elusive emotion
*by M***4 on May 12, 2019*

The is not your basic gratitude journal nor a dry or sappy notions to develop Happiness! Gratitude is taught in this wonderfully written book as one piece of the happiness puzzle, albeit, a decent sized part, but Dr. Beeker adds the essential nuance that it must be mindful and genuine thoughts of gratitude! And there are many other prompts to work on developing our happiness, each appropriately spaced through the week. None of the evenings reflections are long or dreary, but are instead very thought provoking and can take but a few minutes to complete . I will warn you that you may find yourself thinking about them well into the next day which I think is the idea :-)I do like that we are not told to simply suppress our doubts, but rather we should acknowledge and address them, appropriately determining which are valid and which are notAnd I thoroughly enjoy the quotes of wisdom through the ages. The pursuit of happiness is obviously not a new goal, but one well worth ‘work’

### ⭐⭐⭐⭐ Happy Practice = Happy People
*by L***Y on May 11, 2019*

Very thorough review of the academics of happiness. Ever wonder "why" some people are happier? This book breaks down the science of Happiness. You won't get stuck in a rut of giving platitudes. Each day offers you a new way to see your way to happy.
