Courtesy costs nothing. Lower the toilet seat after use. Let the people in the elevator exit before you enter. Return shopping carts to their designated areas. When you borrow something， return it better shape (filled up， cleaned) than when you got it.

The most powerful art is often the most humble.

The tears of the world are a constant quantity. For each one who begins to weep, somewhere else another stops. The same is true of the laugh.

The best ideas often come from the people closest to the problem.

我希望你们也找到自己的路，找到自己的步伐、步调，任何方向，任何东西都行，不管是自负也好，愚蠢也好，什么都行。
