Remembering that it's not you vs them–it's you guys vs darkness.
"[God] wants to bring the man to a state of mind in which he could design the best cathedral in the world, and know it to be the best, and rejoice in the fact, without being any more (or less) or otherwise glad at having done it than he would be if it had been done by another.
The enemy wants him, in the end, to be so free from any bias in his own favor that he can rejoice in his own talents as frankly and gratefully as in his neighbors talents or in a sunrise, an elephant, or a waterfall. He wants each man to recognize all creatures ( even himself) as glorious and excellent things."
- C. S. Lewis, The Screwtape Letters
