Yes, I know someone (family) did Uni, worked in the fitness leisure industry for peanuts and no thanks but enough to manage on. One day chucked it all up and went on a round the world trip, saw all the places and things that were only in books or TV, girlfriend took a gap year from a very good university placement with a 'comfort zone' course.
On their return, girlfriend swopped Uni to other end of the country and a radiography (difficult, but more rewarding) course. He now sells customised longhaul tours to mostly students wanting to make the same break and see the world too. Best of all he continues to travel, so much out there to do and see!!! No money left - but a better life.
GO for it I say, while you can.
