The more you live, the more you learn. The more you learn, the more you realize how little you know.

The meaning of life differs from man to man, from day to day and from hour to hour.
声音是神圣的乐器，我们必须明智地使用它。
"What lies behind us and what lies before us are tiny matters compared to what lies within us."
Excellence is not an act, but a habit.
