Everyone should read this

I very much enjoyed reading the book! The moments where I so clearly recognized my father-in-law's "yellowness" made me laugh continuously. My mother-in-law is partially "blue". The discussions/frustrations they occasionally have our hilarious. Luckily she also has enough "green" inside of her, to be patient enough and cope with the difficulties.
The first time I got to know about the 4 colors was about 12 years ago, when my former employer gave us the opportunity to get an analysis from the "Insights". 2 years ago, my current employer uses the "Kolors" to teach us how to cooperate with each other and with our clients.
At first I was surprised that I got much more "red" inside of me than I originally thought, but on the other hand it is true that due/thanks to my working experience, I developed the skills that helped me to learn to speak my mind (yes, I still am and will always be mainly "green") and to try to be more decisive. That's a good thing.
I can't believe how some of the book reviews are so negative! "Jung was a disciple of Freud, and after his death it turned out Freud wasn't always right. Hence, Jung's work cannot be considered to have any value." Seriously?!
"Jung's work is over a 100 years old and outdated" - does that mean that there is no value left? Come on!
"Jung's theory is not scientifically proven" - how long did it take before it was proven that the Earth does in fact rotate around the Sun? There is no proof yet that there is in fact alien life out there. But does someone really believe that us, humans, our the only beings in the entire universe? How big is the chance?
Whatever it be, the insights in the 4 colors helps me every single day to try and understand people that our different than me: my husband, some family members, ... I would advise reading this book to everyone. The only reason why I give it a 4-star rating is because I do think some chapters are a bit too elaborate.
