Man often overstates the trivial things and understates the vital ones!

Humanity must have a speed of advance higher than the speed of advance of cosmic disasters or big global catastrophes!

Sand can resist to water; but it cannot win. Ignorant can resist to knowledge; but it cannot win.

Our dreams are our precious diamonds; without them, we are endlessly poor. Let us perpetually dream to be overly wealthy!

A completely secure life can be found only outside the life!

Be as soft as possible, if something good and wise wants to shape you; be as hard as possible, if something bad and foolish wants to shape you!

No lake is beautiful without the sky, without the mist or without the trees and the autumn leaves! No beauty is beautiful in itself!
