The book is about, what and how to reach higher levels in corporate ladder from where you are now. Book explains about small consistent workplace habits which can make lot of difference which help in moving to next level.
I felt the content is similar to any of the other self improvement books. If other self improvement books are read, this may not a must read and can be given a miss.
I am not sure, if the workplace habits explained by author can be related to current corporate structure and how effective is it, as i think some of the habits will hinder timely execution of projects.
