Success Built To Last

I am currently reading a wonderful book called Success Built to Last-Creating A Life That Matters by Jerry Porras, Stewart Emery and Mark Thompson http://www.successbuilttolast.com/.
I bought the book this past Wed. and I am halfway through with it. The main message that the authors of the book are trying to get across is to redefine our perception of the word "success" as we now know it. Our culture has been indoctorinated into believing that success is all about wealth, fame and power. The book is trying to change that perception by looking at success in a 20-year spectrum. By taking a long-term viewpoint, Success Built To Last (SBTL) makes a pretty good case that money, fame and power will not make you happy and therefore they cannot be benchmarks for success. One of the more interesting quotes in the book so far was that "despite acquiring material luxuries undreamed of even a few decades ago, there is a rising epidemic of clinical depression and suicide among the wealthiest citizens in American, China and other rapidly growing economies..."
One of the first points that the authors bring up is that unless you can find and pursue a life of meaning, success will prove fruitlessly elusive. "Passion" is a requirement of long term success. Larry Bossidy, author of Execution: The Discipline of Getting Things Done http://www.honeywell.com/execution/toc.html
is quote as saying "Only by loving what you do will you actually do more and do it better than the person sitting next to you." "Passionate people spend twice as much time thinking about what they've accomplished, how doable the task ahead is, and how capable they are of it" said U.S. Army Brigadier General Clara Adams-Ender.
For every person who is half-hearted about their work or relationships, there is someone else who loves what they're half hearted about. This person will work harder and longer. They will outrun you. page 35 from Success Built To Last.
Much of what I've read so far sounds faintly similar to the dogma of Dr. Stephen Covey. As a long time fan of The Seven Habits of Highly Effective People, this is in no way intended as a sleight to the authors, but is in fact a compliment and I also don't infer that the authors weren't original. Nothing could be further from the truth. The books findings were based on actual facts and case studies. The only reason that I mention the similarities is to draw the connection between the two books. Dr. Covey has spent his life espousing values like "passion" and "meaning" and it's nice to have actual case studies that reinforce his work.
As I said, I am currently only half-way through the book, but I will continue my review once I have completed it.
