That sounds both exciting and a bit daunting. I have absolutely no experience in this but …Buy plenty of insurance :)
Some of the cleverest people I’ve met were not university grads. Tradespeople constantly solve problems and find creative ways to do things. Plenty of Uni grads are clever and creative, too…it’s just not the only way to measure competence and skill.
I was lucky enough to find a mentor when I first came out of high school…probably saved me from a life of labouring. Best of luck.
