I would have gone into the military after high school.
I agree. I had talked to a Marine Corps recruiter several times and almost signed up. Looking back across 35 years...wish I had.
If that's a little too corny for anyone, probably my second biggest regret is not saying "yes" to the two lovely ladies that propositioned me (at a party, not on a street corner) with a 3-some. I was too much of a good wingman, a buddy of mine had a tremendous crush on one of them. In retrospect, he never would've known, heck, he ended up marrying someone else anyway...
