First thing, it really depends on what type of sub you want to go to. Tridents or "boomers" are usually more predictable and have more personnel than fast attacks. Tridents also are extremely large and more spacious than fast attacks. I am a fast attack sailor myself, and recently toured a trident in the shipyard. It seems like better quality of life and like the crew is more happy in general, but hey, if you like going to sea and a relatively unpredictable schedule along with SSN (Saturdays, Sundays, and Nights), then by all means go fast attack. That's what we're all about, man. No sarcasm intended. You have to enjoy your job so much that you would rather be at it more often than you are home. And that is the bottom line, really. A positive attitude will help you along the way, and stay away from the "mopers", or people who have given up on their duties and are more interested in their prospective transfer date than doing their job. If you keep to it, submarine life can be rewarding. Its an elite group regardless of what anyone says and most regard submarine sailors as the most disciplined in the navy, there's a reason for that.
