I saw the words I used as title at the back of someone's shirt some weeks ago. However, I didn't get the chance to see the front part. It triggered a lot of reasoning... which I would like to share with you.
In war, there is a basic rule, upon which others lie: do not be defeated. This is understandable, as it is only those not defeated that could charge towards victory.

It is okay to charge towards victory, plunder, success, promotion, and the likes. Just remember, only those undefeated could proceed. And only these could return home.
In the words of Isreal Hands, Dead men don't bite. So, to win, stay unbeaten. Stay undefeated!
