Quick and easy read. This book is short but full of pearls. Published in 1957, but still very much current when it comes to predicting, understanding, and managing human beings. One of this author's famous quotes is "Work expands so as to fill the time available for its completion."
Full of interesting anecdotes, it is a very colorful and memorable book. It is not sophisticated, and show some outdated facts and data, but the substance will never be outdated. I recommend!
