If only someone had shoved a book in my hand, when I was young, that gave some guidelines for leading an effective life full of achievements and success.
The book wasn't forthcoming though and, like most people, I have muddled through life.
I have now reached an age when I have developed my mind and accumulated enough information and experiences to write my own book.
Whether you agree with everything in this book is immaterial. At least it is a thought-provoking head start.
