More than 2,500 years ago, Athenian General Thucydides said, "We must remember that one man is much the same as another, and that he is best who is trained in the severest school."
As I've said countless times, had Thucydides lived in the 21st Century, he almost certainly would have agreed that one of the world's "severest schools" is the six-months of absolute hell endured by young Navy SEAL candidates hoping to win -- after an equally tough post-training period with "the Teams" -- the coveted "trident" badge: symbol of the SEALs.
