Joining the military is not like any other job you would typically find. It is a lifestyle, not just a job.
In the beginning it is a bit intimidating however, after you get to your first command you will settle in and start learn at a very fast pace. As you go through your career you will be given training opportunities that will develop you professionally. Not to forget to mention the travel, I have lived all over the US as well as in Europe and Japan. It has been a great experience for me, I will miss it.
