邪恶获胜的唯一必要条件是好人袖手旁观。

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 best way to predict the future is to invent it.
