Life changing and immensely comforting
Format: Kindle
A well written and descriptive book on a topic that I had never seen before but described me to a T. This book lead to great clarity about why I feel the way I do, how to embrace the positives, and best of all, how to navigate a world where I am different from most through peace and empowerment. An excellent read even if these traits don't apply to you, as understanding the inner workings of others and allowing each to be his/her own person is where we learn to live in harmony. Excellent book.

Not a new personality type -- one of the 16 Myers Briggs types
Format: Kindle
The author claims to have identified a personality type that differs from the 16 types identified in the Myers Briggs Type Indicator (MBTI). Among those 16 MBTI types, 8 are extraverts and 8 are introverts. The author refers to those 8 introvert types as a single personality category, and then he tries to differentiate them from the type he proposes: the Otrovert. However, his description of the Otrovert is a detailed, accurate description of one of the 8 Myers Briggs introvert types: the INTJ. So he has not identified a new personality type; he has simply isolated one of the 16 MBTI types and elaborated on it. He does an excellent job of explaining the nuances of the INTJ personality, but he has not identified something new. I would have rated this book 5 stars if it had been presented as a closer look at the INTJ type. The book "Type Talk" by Kroeger and Theusen is the preeminent authority on the MBTI, written by people who qualify instructors to administer the MBTI instrument--find it on Amazon at this link: https://www.amazon.com/Type-Talk-Personality-Types-Determine/dp/0440507049/ref=sr_1_1?

the book for me
Format: Kindle
This has been the best book I’ve read in 2026. I finally understand who I am. I can’t tell you how many times I’ve wondered what’s wrong with me. Turns out …. Nothing! I have struggled with the constant message of “you need community” and the internal desire that cringes at the thought of it. Isolation is bad but select community is perfect. No more shame for needing alone time or just wanting to stay home. I’m normal - just an outlier ! Thank you so much for the valuable insight that has given me such revelation and relief about how my mind and emotions work 💜

Excellent introduction
Format: Kindle
This is a well-written introduction for quickly learning how to use Ollama to run LLMs on your local machine. The book is light on theory but very good for facilitating hands-on experimentation. Only minimal Python experience is needed. Contrary to another reviewer's comment, the source code, which can be copied from the Kindle version of the text, is also readily available by emailing the author at the address provided. The final exercise in the book leads you through generating a RAG application to use Ollama to process your own documents without having to make them available to an external server.
