Can a book really tell you why you were born? Probably not.
But Chapter 4 of Inner Leadership will ask you to define what it will take for you to have lived a worthwhile life. Chapter 5 will enable you to uncover your values and your life purpose. And Chapter 6 will show you how to focus these into a series of specific, tangible, achievable, inspiring visions.
If this doesn’t count as “finding out why you were born” I don’t know what does. But only you will be able to decide what counts for you.
