Stephen Covey back in South Africa
He is the author of the very successful and absolutely amazing book, The 7 Habits of Highly Effective People. And I recently listened to a terrific interview with him by Tony Robbins.
Having read the book a while ago, I never really appreciated its impact as much as I do now. And I am integrating the principles into my life. You may also want to check out his new book, The 8th Habit.
