What trade is good for f up

I'm 17 about to be 18 and 3 months and I really want to leave home and I really want to work and I'm already doing construction i cut tree's and build walls. I failed every subject at least once and I failed math twice in highschool. Like I said I really want to work and make something with myself but I being realistic I don't think that's not happening . I kicked out of school twice for my grades.
