Sage advice given to me just before a six year term in the USN. While your in you will hate it, it will seem like time stands still and your enlistment will go on forever, but don't worry time moves faster that you think, and someday in the not too distant future you will look back on your time in and remember it with fondness and longing. It will be one of the most exciting and fun times of your life and it will never be forgotten.
So I say enjoy it while your in, take advantage of every opportunity it provides, and know that you'll be a better person when it's all over with!!
