This book is so average. It basically tells teachers to always be positive and they will have a great impact on students. There are a few pieces of advice that I think are useful for all teachers, but a lot of the suggestions can only work for certain teachers. This book says that sarcasm should not be used by teachers, but I know many teachers who can effectively use sarcasm to help their classes. At least this book is an attempt to help teachers, but I think you should take the advice with a grain of salt. 

This is by no means a bible to live your teaching career by, but there is a reason it was gifted to me in my first year of teaching. Alas, if only I had time to read in my first year on the job.

Herein lies a blueprint to build a successfully managed classroom, to support your students to become self motivated and caring humans in this confusing world. This book is greatly positive and focuses on what you can do to become better in every aspect of your job. It is full of good reminders for anyone, regardless of the number of years they've spent in the profession, but particularly for early career teachers who want some guidance on how to manage themselves in a professional manner.
