I did. I was a goof in high school, my buddy had the most cuts in the school, I wasn't far behind. Suspensions, cuts, etc., and the dean of students called me in the continuation school I was in and told me to not come back when I turned 18. I took a GED test and have an "equivalent". I landed a good job but it ended and I found myself with three kids and a wife to feed and no craft. I very QUICKLY determined that underground mining was not my cup of tea. I got a low paying job and went to vocational school while working full time. Sleepy, tired but determined. Yes, it was worth it and I now stress that no matter what, the more education you can get, the better. Work out a plan "A" plan "B" and "C" and be prepared to change or adjust as the economy shifts all over the place constantly.
