War is a bloody, killing business. You've got to spill their blood, or they will spill yours. Rip them up the belly. Shoot them in the guts.
Make the mind run the body. Never let the body tell the mind what to do. The body will always give up.
You need to overcome the tug of people against you as you reach for high goals.
Lack of orders is no excuse for inaction.
Always do more than is required of you.
You must be single minded. Drive for the one thing on which you have decided.
