Stairs elevate you; ethics elevates you; goodness elevates you; awareness elevates you; wisdom elevates you.

Every man is a door; when the door is closed, just search for the key gently! Remember that every door has a key!

Anything easy teaches you nothing! To learn something, have some difficulties!

Violence is the tool of the barbarian; aggression is the method of the primitive; bloodshed is the way of the savage; cruelty is the manner of the brutish! To be called as a 'civilised,' man must be peaceable!

Silent moments are valuable! They give you a good opportunity to design new paths in your life!

For mankind, science is the only real candle in this dark universe; all other candles are fake! Science is our only real hope; all other hopes are fake! Remember this!

Be clever and do not build walls, because in the future they will bring only shame to you!
