If you live in a dirty big city, it means that you surely need a pastoral life to make yourself clean!

Science is a seagull, it knows the sky; it is a squirrel, it knows the forest; it is a mole, it knows the underground; it is a dolphin, it knows the ocean! Science is a multi-talented creature!

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

The clever cannot catch the genius; such an attempt is just an act of trying to catch the shadow of a flying bird!

To remain silent for only one minute is a serious punishment for a gabby!

When you are grateful to the rain, do not forget also the clouds! When appreciating something, be fair enough also to appreciate the sources that created it!

What a magnificent accomplishment to be able to stay alive as an innocent lamb in the land of guilty wolves!
