This is my first reply. There are times when I'm looking to hire somebody and I would like to connect with prior nukes, so I thought I'd do some looking on a blog site.
I'm a prior sub MM1, got out in 1998. I manage the Maintenance, Facilities, and Engineering for a privately owned company now, making 6 figures. I never received my formal 4 year degree. But I have to say that I'm the exception and not the standard. I would ask you the question of what you want to do? What kind of work is satisfying to you? This is the time and opportunity to be truthful. If you like to work with your hands and do technical work, then you can get a job as a technician and work your way up to planning and scheduling, and maybe a supervisor job. If you like to lead people, organizations, and see yourself in a management position (technical or operational), then I recommend going to college and getting a 4 year degree, either in engineering or business. You will do well in school if you made it through the nuclear pipe line, it's just a matter of patience and commitment. Begin with the end in mind.
Either way you'll start out at an entry position, either as a technician, operator, or supervisor. From there it's who you know, how you present yourself, and your body of work that will determine the course you take in your career.
