Fulfillment

A happy life is a fulfilled life. A fulfilled life consists not only of cherishing joyous occasions, but mastering the obstacles. A sense of achievement is necessary to feel happy. You can only feel it when you have achieved something by overcoming your troubles.

Teaching

If teaching was all about reading, then we would have no human professors. Only books. Teaching goes beyond a book, not within. Beyond the book means teaching works within a student. Teaching is not about completing curriculum. It's about helping the student discover their destiny.
