To be fair mate, if you're getting out of college at this point without knowing where to go, that is mistake number one that you have already made. I would not be surprised if degrees become a prerequisite in the future, and as others have said, another year in education is not long compared to your career: you may want to rush into it now but it is quite possibly a big mistake. Few people will employ or sponsor 17/18 year old, especially without A-Levels. AS-Levels are not really a hugely recognised qualification beyond GCSE, and additionally, whatever you may feel right now, there is no need to rush in as soon as you can. There are jobs and there will be for a while.
You have the opportunity to open your options; why close them prematurely?
