If you have feet, walk! If you have wings, fly! Whatever you have, use them! Don't let them to rust!

Let the cats rule the world; first thing they will do is to increase the number of mousetraps! Let the rats rule the world; first thing they will do is to increase the number of dogs!

To die for a cause is insanity; man's greatest cause is to live; his biggest purpose is to stay alive! Only fools die for a cause! Which cause can be superior to man's life?

There is no need for the street lights in the Street of Love; all is already bright in there!

By respecting the trees, you prove that you are a person who deserves to be respected!

Open the door by yourself instead of waiting the door to be opened by itself!

The footprints of a free-minded man are always towards the forward direction.
