While I never reached Malcolm Gladwell's magical 10,000 hours of experience to master my skills as a sub-rider, I did learn a few things during my time aboard submarines. Here is a short list of a few things I learned (not listed in any particular order):
1. You are eating someone's chow; they are not happy about it.
2. You are breathing someone's air; they are not happy about it.
3. You are drinking someone's coffee; they are not happy about it.
4. You are sleeping in someone's rack; they are not happy about it.
5. You are using someone's water; they are not happy about it.
6. Screw the mission, clean the position is not my favorite slogan.
7. The Auxiliaryman of the watch is not your buddy.
8. Open/closed valve signage is really important.
9. You can never have enough amine.
10. Fires underwater terrify just about everyone.
11. Underwater, SWO pins aren't impressing anyone.
12. Same for Naval Aircrewman pins!
13. If you're not a qualified submariner, why are you breathing?
14. This life is not for everyone.
15. Some believe this life is not for anyone.
