How can I stop talking about the military?

I am a 22 year old Operation Iraqi freedom vet.. and am currently in the Army National Guard ever since joining the military in 2005 at 18 all I really do is talk about the military. It has gotten to the point where I relate everything in life to the military and annoyed a lot of people. I am in no way a show boater or bragger its just that its always on my mind.
