So you'll never regret, but you will have some of the best days of your life and some of the worst days of your life in the U.S. Navy, you know what I mean? That says -- that means you're living.

That means you're not some pussy sitting on the sidelines, you know what I mean, kind of sitting there saying, “Well, I should have done something with my life.” Because of what you're doing now, you're not going to be laying on a shrink's couch when you're 45 years old, say “What the hell did I do with my life?” Why? Because you served others; you served something bigger than you.
