Everywhere is a battlefield!
Never let your guard down.
I've seen plenty of time on the battlefield. The way I see it, there are two things that are invaluable when you're out there in the chaos.
One is absolute, teeth-gritting determination. The other is a friend--one who you trust implicitly to stand at your back.
Just remember, utilize your determination to look at the big picture. A calculated retreat today may turn out to be the key to tomorrow's victory.
