why would you choose long term lifestyle and short term when you can just combine them.
you have to study but do not forget about living ur life go to few partyes and also hang out with EVERYONE!--thats very important if you are good with entire school and you have no enemies you wont have nothing to worry about there will be no pressure and it will be easyer for you to sit down and study. it will bring you nice memories when your old and you have kids and all that stuff.
so go there, study hard, get known with lots of people(starting from day ONE) and graduate!
