This book is the follow up to the successful Halftime. it is a shorter book with short easy to read chapters that were developed from the author's musings part of his website activeenergy.net. There are also questions at the end of every chapter that are more for personal reflection than group use. The author recommends using a journal to record thoughts and answers on what he calls the second half journey.
Bob was heavily influenced by Peter Drucker and quotes him as one of his influences. It may be hard for some of us to relate to Bob's affluent background, but he assures all of us that having a lot of money is not a requirement for a successful halftime. All it takes is a desire to be used by God in this second half of life, and use your talents and energies to the best of your ability.
He spends most of chapter 12 comparing his approach to aging with Philip Roth's novel titled Everyman. He calls it the "antitext on aging well." It describes the exact opposite of what he is trying to do and encourage others to do as far as leaving a legacy, having regrets, envy, and remaining faithful. Sometimes it is good to understand the end results if you make the wrong choices.
It's not necessary to read Bob's previous book, Halftime, to understand his point, but it would be to get the most out of it. I would recommend it to those who want to go further in halftime.
