During a leadership course led by her, Naju Medhi mentioned this. She did mention that she read this from the book 7 Habits of Highly Effective People by Stephen R. Covey. So probably the citation should go to Stephen R. Covey.
However, Naju brought that sentence in a way that somehow I just cannot forget it.
