if you were in your 2nd year, my advice would have been to quit.
go NS. spend that 2 years and think thoroughly what you want to do.
but now that you're in your 3rd year, and now probably being your
2nd semester, what's the point?
you're going to graduate in 2 months time.
go ns. think things through carefully. look at your own interests,
are they viable as jobs?
for eg.
i've got this bunch of friends interested in japanese sci-fi shows
(kamen rider, sentai, godzilla etc). some just finished Os, some
finished As, some finished poly, some just ORD. but they've all
banded together, and are going to produce a locally made sci-fi
show, and several of them, through this project, have decided to
pursue filming as a career.
