I have a friend who speaks of knowledge as an island in a sea of mystery. . . . We dredge up soil from the bed of mystery and build ourselves room to grow. And still the mystery surrounds us. It laps at our shores. It permeates the land. Scratch the surface of knowledge and mystery bubbles up like a spring.
Gratefulness is the key to a happy life that we hold in our hands, because if we are not grateful, then no matter how much we have we will not be happy—because we will always want to have something else or something more.
