Go to Uni, have a good time and decide about being a Pilot after, at least you may have a backup plan for a career if you decide against flying so long as you have a decent degree. Most airlines are looking for tertiary education as the minimum entry requirement anyway. Only do the flying if you can't imagine any other career that you will be satisfied with. If you love flying that much, it will carry you thru the inevitable s##ty bits and the debt. GL
