I'm 50 years old. Graduated from high school on a Friday in June 1987, and went to work for a tech company on Monday. 20 years later I got an AA degree in Fashion Design in 18-months, because hiring managers needed to be able to mark the box "College Degree?" with a "Yes", when I was applying for jobs.
I never got to experience college. Intense learning environments. Honing your mind and skills against instructors and classmates. Doing the hard work of finals and timeline management and learning hard shit. And then fully letting go, with fellow classmates, in a bacchanalian release. Feeling pride for my mascot/team/school (because of Stockholm Syndrome) and having that connection with people for the rest of my life, because of our shared experience with that school/team/mascot.
My life is amazing. My skills are at the top of my game, and I get paid handsomely for it.
But that doesn't mean that I don't miss what you are about to experience... I'm having some major twinges of jealously...
