Soldiers, when committed to a task, can't compromise. It's unrelenting devotion to the standards of duty and courage, absolute loyalty to others, not letting the task go until it's been done.
The most important thing I learned is that soldiers watch their leaders' actions. You can give them classes and lecture them forever, but it is your personal example they will follow.
Keep your face to the sunshine and you cannot see a shadow. In every day, there are 1,440 minutes. That means we have 1,440 daily opportunities to make a positive impact. The only time you fail is when you fall down and stay down.
If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer defeat. If you know neither the enemy nor yourself, you will succumb in every battle.
