A Solider's Creed
The true soldier fights not because he hates what is in front of him, but because he loves what is behind him. -G.K. Chesterton
Try it another way:
I will not fear what is in front of me because of the love that is behind me.
Make the mission about love, not fear.
Love what you do.
Love who you do it with.
And always put them first.
