Stay at college, complete the course, do as well as you can. I dropped out halfway through a 2 year electricians course when I was younger, at the time I decided I didn't want to work in the field. One of my mates is a sparky now and earns over £50,000 a year, about twice what I earn, so did I make the wrong choice? Also, he doesn't hate his job.
