dont worrie mate 
why giVe that type of face? rememeber this, there are thousand of
people going in and out before you
and im sure that,
lots of 'em have alot of unforgetable experience and memories, you
will soon have a BUDDY and get to know whats ARMY is all about.
most imporatntly, i trurly believe that, army will really change
you! FROM A BOY TO A MAN

my advise, try your best in whatever u r doing while you r there,
and....when you r order to do sometime, JUST DO IT (with care ofcoz
) and.... never ask
urself, WHY M'I DOING ALL THIS SH.IT OR SOMETHING LIKE THAT
as if you gonna
think this way, life down there will be real bad for you

good luck and with all the best blessin 
cheers
