"Only the one who gives himself up is lost" Hans-Ulrich Rudel

"Fun" fact: This guy was a convinced Nazi who basically destroyed two Russian tank divisions alone. I told this quote to an African American friend when he was struggling badly and had to go abroad for a job and it has inspired him ever since. https://en.wikipedia.org/wiki/Hans-Ulrich_Rudel

Beowulf has a similar quote: "fate often enough will spare a man if his courage holds"
