Good self-improvement book

Came across a good book at the Resort Library :

FYI -
For
Your
Improvement

by Michael M. Lombardo & Robert W. Eichinger

A book about self improvement, and identifying your own weaknesses and strengths. The book also explains in details how the under-using or over-using of a certain trait can be counter-productive... There are also ideas and ways on how one can improve and correct one's behaviour. You do not need to read the book from the first to last page, the book is designed in such a way that you can zoom into that particular 'competency' that you wish to improve and get to work on it immediately.

An interesting and excellent book if you feel you're stuck somewhere, want to progress and move upwards or if you're a mentor or supervisor, the book can help in providing feedback on how you can help your mentee or subordinates understands their strengths and weaknesses, hence helping them to grow and develop.
