yeah i hear ya man. I'm in college majoring in mechanical engineering right now, and i think all the time, what if i end up failing? What am i gonna fall back on? I know i dont want to end up working construction the rest of my life. But, i guess what i do is kinda suppress that to the back of my mind and just tell myself that it'll end up ok. but i'm still quite uneasy about what the future holds for me (job, house, wife/gf).
