Do you know George Eastman? He's founder of world-famous Kodak that brought photography and images into our daily life. Surely, he was one of the wealthiest men who ever lived in history. Dwelling in a mansion of about 30 rooms, he liked organ music so he hired a regular organist to be part of his household. One day, while eating a meal and listening to organ music, he took his gun and said, "I finished my work. Why wait?" Then, he pulled the gun into his head. How tragic. William Shakespeare once said that our lives can be like an "idiot's tale, full of sound and fury, signifying nothing." Indeed, the greatest tragedy is not death ... but life without purpose.
