Finish your A-Levels and work hard at them, then go for being a flight attendant. You might find something you really want to do later in life that requires a degree... and this will be MUCH easier to pursue if you have NOT already been to University (and especially if you have a decent job that means you can save).

Far too many people feel like they're "supposed to" go to University straight out of school, end up doing something they don't really have any passion for, and then don't have the option of going back again later in life when they HAVE found something they want to do.

I honestly would recommend that almost everyone takes some time, until at least their early 20's, before applying to University. Gain some financial security / independence and adult social experience first and you'll be much more likely to make a success of Uni (if you do eventually decide to go).

There are a FEW exceptions to this where people straight out of school really do have a solid idea of what they want to do (e.g. I've known people who were pursuing medicine or computer science etc. since the age of 14 or 15) but generally I think people go far too young.
