This book had a lot of information to offer-- some of it interesting, some of it very drawn out. There were a few chapters I skimmed because they just didn't seem relevant for me, but there were some chapters I read in one sitting because I was so curious about the topic. I think it might be a good little resource for people who are just starting to get into MBTI. I've been studying MBTI for a while so a lot of it was like a review for me, but I still grasped a few new, interesting things. It was just boring for me overall.

Two little disclaimers to keep in mind: 1) It was published in 1988, so some of the information/examples are a bit dated. 2) Sometimes the descriptions of the different functions sounded like they were written by someone biased against those functions, which I was not a fan of.
