After GCSE's? (ft. the future)

Ok, where do I start?

I'm currently in the process of completing my last few GCSE exams. I feel like I've done pretty well in all of my exams, and I revised a fair bit with the mindset that I don't want to be disappointed in August / have wasted 2 years for grades I feel could have been better.

It's crazy how fast they've come and gone, and it doesn't feel like I've actually entered the GCSE period - I'm not sure how else to phrase this, really.

I'm just not sure what happens after GCSE's. I feel like for the last 16 years I've been guided into everything I want to do in life, academically wise. I guess you could say I'm a bright student; I generally get A's and A*s in my subjects and that is what I have been predicted to get on results day. Everything has been straightforward enough, not many hard decisions to make.

But now, I'm starting to realize that I need to think about my future, and I seriously have no proper idea of where I see myself in the next 2/5/10 years. I'm extremely happy and appreciative that I have a 'knack' for most things academic, and this results in most people thinking I love school and all my subjects etc.

I don't. I like going to school and seeing friends, and I'm ready to work as hard as the next guy but I really don't see myself as being smart or 'of great intellect' - it's just not me. I'm a pretty simple person and I don't see myself ever going into 'that' world of studying etc.

I have already decided to do A levels - specifically Maths, Further Maths, Chemistry and Economics as these were the 'least unappealing' subjects I could choose. I'm not really worrying (too much) about A levels, as I do work really hard. I just don't see myself enjoying it much because I have this creeping worrying in the back of my head that after two years, I have to make a pretty big decision as to what I want to do in life - real life.

The 'logical' thing (and the thing that most people/my friends/ family) to do after A levels, which is going to university. My family and teachers think that I am capable of going to Oxbridge / LSE/ Imperial etc. but I don't really want to go there! The people that go there are all intellectuals and very well rounded - I feel like I would just not be able to get along well with these sorts of people. I come from a rough-ish area of the UK and I'm very comfortable with what I have now, I don't want it to change.

Then after university?! I see myself owning a business of some sort (mostly because I hate taking orders and I don't like the idea of working 9-5 for 40 years; I wanna be flexible you know) but I just have no idea of how I get there.

TL;DR - I'm scared and worried about what is gonna happen to me in the next few years, I'm not a 'super learner ultimately hyped about learning yay' sort of person and I don't know what to do about it.
