move on don't worry about it, and that doesn't make you a failure, because you didn't know what you wanted to do. other people don't go to college, so don't feel like you did something stupid (some drop out of highschool
). you still have a long time to live (unless you're 40 or older and just now choosing a profession) and a long time to look at the future. just think you have a career opportunity that you'll enjoy and have an interest in, you just have to follow through with it unless that's the problem you're talking about. if that's the case I probably not going to be very useful to you, sorry.
