I will say, the economy was in the crapper when I graduated high school so everyone went to a junior college. Before the first semester ended, 3 of my buddies flunked out and decided to join the Navy. I wasn't flunking but also didn't like short hair back then (I wear a #1 cut now) so I stayed in college. All 3 enlisted in January and it did teach the discipline and motivation. They all left after their minimum service years and did very well afterwards. None of them were seal material but it did make them grow up.
