Self-development books abound. Few stand out.
Here's one which stands out. First of all, the ratings are very good to excellent (4.5 stars at Amazon; 4.03 (809) at GoodReads). And it's not a self-pub, or published by a fly-by-night operation of questionable quality--it is published by no less than the AMACOM (The first part stands for the prestigious
American
Management
Association).
http://www.amacombooks.org/ for the book publishing end of the AMA.
It is Focal Point: A Proven System to Simplify Your Life, Double Your Productivity, and Achieve All Your Goals. It sounds like it may be much like Stephen Covey's bestselling First Things First.
It's got 252 pages, so it's substantial.
The Kindle ebook price is only 99 cents right now!
