I didn't serve in anything Chandler, but my adopted son did, 7 years on HMS Somerset, type 23, engineering, navy put him through his degree, he has had some colourful stories, like chasing pirates and a exchange program on a USN carrier for a few weeks haha proud of him though, he got a vet medal for it and another 3 years reserve, still civvy engineering now.You still took the initiative. Good on you.
My only excuse was "I didn't have to." I was 2 stamps away from going to the US AF Academy after college... and a job came up. Still haven't figured out if I made the right choice.
