My ratings are always based on how much energy a product generates in me. Sometimes the trigger is usefulness, at other times it's the production quality or other things. That means that I ignore aspects of the product that aren't relevant to my focus.
In this case, the four stars are based on the fact that this book makes me muse about myself and my life and makes me smile at the same time.
I'm a nut for off beat playfulness that balances between nonsense and seriousness. This book (as well as most book by Prof. Oddfellow) does just that. Obviously the 'One's elf/Oneself' is the running theme here. I can see how you can look at it as lame wordplay. To me it isn't. Something weird happens if you place your personality traits, ego and whatnot in the elf of your choice. One separates one's elf from oneself. Distancing yourself from yourself is always a good way to see bigger pictures and wonder about why you're behaving the way you're behaving. It opens up new possibilities and ideas. —G.
