Dun lose sleep over enlisting, its not worth it. Cross the
bridge when you get to it.
Just go to BMT with an open mind, check your expectations at the
door. Make friends fast, cause they'll be the ones who will help
you get thru the tough times.
The jokers in my section really helped me 'survive' during the
darkest periods.
And must remember to have fun, no point dreading about everything.
Its not like you have any other choice, so might as well make the
most out of it.
What you take away from 2 years of NS really depends on
yourself.
