Pre-law, economics.
But Navy recruiters slapped some sense into me my sophomore year at Creighton University, and I signed up for the AVROC program, abandoning law school.
It was a tough sell, since I was also nearly failing my (hated) second year of mandatory, Army ROTC (A's and B's in all subjects, but a shaky "D" in a supposedly "given" grade, Army ROTC.)
Nearly equal time in the F-4, F-14, and A-4. (And a little fun-time in the CH-53, P3-C, S-2, and C-131 among others, and even a cameo 1.0 in the then-new, F-18.)
Like A4's, my studies involved "wine, women, and song." Rather than a TR-4, I had an ugly old green Rambler…. But my seats folded down, and everyone including all blondes on campus knew it!J
Our fighter squadron had superlative officers - Some with forestry, ancient languages, history and philosophy degrees, as well as the more normally expected.
I got most of a Masters, but found I didn't need and couldn't finish with my deployments and airline schedules. (When I figure what I finally want to be when I grow up, I may re-apply…seriously.)
Flew fighters, been around the world a few times, been shot at, proved to myself what I was capable of, and did 10 times more than I could ever imagine, and am a happy old/young man with absolutely no regrets and tremendous memories, and irreplaceable friends and compatriots.
[My only regret – if I had one – is that I can't do it all exactly the same, once again.]
IOW, no regrets!
