Flying logistics is the hardest thing you'll ever do in your life.
You won't be thanked for your work
No one will remember your birthday
People will take you for granted
And your life will be in constand danger.

You'll ask yourself: "Why do I do this?"
And ultimately you'll know:

It simply needs to be done.

It's the most rewarding thing you will ever do.
It's something worth dying for.
