For myself (probably one of the youngest members here, in my early 20's) I went to university... but was never satisfied with how mundane and thoughtless much of the work was. It felt like you were working to please someone else, through learning skills that benefit you in a potential job, rather than skills that'd benefit yourself, throughout your own life. Hands on skills. Time-honoured "life skills".
I think your youngest years, while you're in the best of health, are best spent exploring (hence Overlanding) and experimenting with all the many ways you can spend your time. I love learning but dislike a lot of the ways you're "supposed" to do it in "higher education". I've always liked the idea of self-sufficiency and find the idea that I can just rely on someone else to get my food, or cook my food, take care of my safety, repair my stuff, to be precarious. This is why I decided to to teach myself metalworking, auto repair, bushcraft, woodworking, electrical diagnostics, circuit design, and most recently stick welding (though I did MIG in high school). Soon, I hope to grow more of my own food. It practically ran in the family: my grandpa was a blacksmith/cobbler from Russia, cousins are farmers - being handy is in our blood. For a long while, I've been developing film for myself and others, and teaching kids in my old highschool how to make real silver prints too. I recently completed a steel bumper for my Subaru, and fabricated an aluminum sculpture for a friend, while teaching her how to do it on her own next time (it was great to see how enthusiastic she was)! To the credit of my generation, plenty seem interested in "maker" activities like 3D printing, sewing, clothing repair. But over here, relatively few of us know how to take apart an engine or lay beads of 7018. On the other hand, those skills are in demand.
I definitely get weird looks going to uni with the occasional arm and shirt covered in grease... but there is a feeling like no other when you make something with your own two hands out of nothing but raw steel, and there is immense pride in knowing that thing you designed and built, can practically improve your life, make your rig more capable and be able to see more sights, or just be plain beautiful. Especially with my generation, it's something a lot of people are both fascinated and confused by; if only because they can't imagine how you could possibly design and build something out of seemingly nothing...
