When I was on my gap year, I really wasn't excited at all, as uni was either
a) too far away to get excited about
b) back in the UK, and going to uni meant leaving (solo) travelling behind and going back to cold Blighty (boo! I cried on the plane on the way home)
c) too soon - I returned to the UK 10 days before starting uni, and there was a bit of a mad rush to get everything ready, so I didn't really have time to get excited.
And honestly, now? I love my uni!
