You cannot be disciplined in great things and undisciplined in small things. Brave undisciplined men have no chance against the discipline and valour of other men. Have you seen a few policemen handle a crowd?
Discipline must be a habit so ingrained that it is stronger than the excitement of battle.
No sane man is unafraid in battle, but discipline produces in him a form of vicarious courage.
There is only one sort of discipline, perfect discipline.
You cannot be disciplined in great things and undisciplined in small things.
