dude, you will most certainly regret that decision for the rest of your life. while a G.E.D is basically the same on paper, it's not the same in the real world. in the real world, it says that you couldn't even manage to finish the easiest fucking thing possible....high school. you had to take the easy way out. you have the rest of your life to ski, travel the world, etc. finish up your last year or two, and then explore those options. i absolutely 1000000% guarantee that you will not regret the decision.
now i know hs blows while you're there, and everyone is in such a hurry to get out, but once you do, you're slapped with the real world. enjoy the rest of your time there. make the most of it. but please, heed my advice when I say finish it. you'll think back on this in 10 years and be glad you did. trust me.
