In the enemy's territory, be as silent as the owl's wings; in friend's territory, be as cheerful as the nightingale's songs.

* General Napoleon says that ‘Never interrupt your enemy when he is making a mistake.’ Well, I suggest doing the opposite: Interrupt your enemy when he is making a mistake. Don’t be opportunist; don’t benefit from the weakness of your enemy! Be just even to your enemy! Try to find a way to defeat him without harming him; prove to be as intelligent as to find such a way! Only then, your victory will be meaningful and honourable!

When the enemy is awake and around, don't ever shut your eyes even for a single second no matter how sweet and tempting the sleep.
