Query: Timeless, practical advice, immediately implementable

In this short book are some of the most trenchant, clearly-written statements on how to be an effective executive ever written. It contains some philosophical statements, more real-world examples, and most importantly, it details actions the executive can take to become immediately effective. I wish I had read this 20 years ago!Other books like Good To Great and Built To Last are excellent, too, but are more strategic. This is the tactical book, beautifully and concisely written. If you want to be effective, buy this book now. It is brilliant.
