Wars can destroy everything but hope!
Earth is our only citadel in the universe; but we have illogically built many more fortresses within this beautiful castle!
Before climbing the summits, you must first walk in the down valleys!
If you do not like an idea, challenge it with a better one!
Birds don't need bridges to cross precipices and honourable men with honesty wings to cross precipices of slander.
Make no cry in failure! Make no noise in success! In failure, silence; in success, silence! Fly with the same attitude both in the high and in the low altitudes!
