Query: Short but sweet

In life, the only thing that we can count on to stay the same, is change. It disrupts our lives, hopefully eventually for the better. Meanwhile, how do we manage change? Spenser Johnson gives us his suggestions in the book "Who Moved My Cheese?"I have read self-help and managerial books consisting of hundreds of pages. After each chapter, I can sum up that chapter in a sentence. Spenser Johnson makes his points succinctly and humorously, in only 94 pages. This is appreciated after some other books I have waded through, containing less insight. This book was definitely worth reading.
