If you are thinking about joining the armed forces in order to get out of a bad personal or family situation, don't to rush to enlist. Don't make this important decision when you are upset, confused, unsure about your future, or pressured by your family.
Many people discover that their problems get worse, not better, in the military. Others find after enlisting that their situation at home improves or that they don't want to be in the military after all.
Don't enlist unless you're sure. If you change your mind after you join, it is very difficult to get out.
