If you are a student, try to be a teacher; if you are a teacher, try to be a student!
Feathers are light; but when they come together, they become heavy!
But just one gram of suspicion weighs heavier than a kilo of truth!

The tragedy of man is that the happy moments of life behave like the birds of the forests: They appear and disappear suddenly!
He who observes the infinite horizons will see the dangers before others.
