And your age really shows in that post charliegarner.
University is what you make of it. Chances are, if you go to a good one, do a worthwhile course and get a good grade, you will have matured and learned a hell of a lot. Yes, a lot I people who go to 'university' should not be there, but if you have a clear goal and are motivated, like any wannabe on this forum should be, then you are likely to gain from the experience if you are academically able. There is so much more to university than the degree itself.
I speak from experience. Unlike yourself.
