Surviving OCS. I've heard the first 3 weeks is the most intense.
1: stretch every night- I don't care how old you are, you will get sore. Stretching is a fantastic way to prevent injuries. Nimitz has yoga mats and foam rollers (they aren't in great shape, but better than nothing). They also have ice, so the ziplock baggies you bring can be used for that. If you need more attention, the
sadistic... umm... helpful ladies at smart will hook you up.
2: be loud when you need to be- there are times when you (and your class) need to be loud. If you find yourself thinking... hmm... can I be louder, the answer is yes. Be ballistic it will literally save you if you are hypothetically, getting sharked during an evolution while simultaneously reaching muscle failure. Also, contrary to what you may believe, it is rude to not be ridiculously loud in the chow hall. When you aren't supposed to be loud, just be silent.
3: do what you're told- easy right? Not really. People really struggle with this one. You are given enough rope to hang yourself. If you are told to study in your room, don't get caught sleeping on your floor or with your feet kicked up.
4: Embrace the experience- it will be the dumbest, but funniest, experience. I always tell people the best memories are made in the worst places and man do I have some great memories. You will laugh at things the DIs say or you may get RPTd because someone has the same last name as you and the RDCs don't realize you're the wrong one (happened to my roommate). These are all things you'll look back on and laugh at.
5: Only worry about the upcoming evolution- it's easy to get caught up in future things, to be honest, worry about the next event. If you are asking about graduation in indoc, your focus is on the wrong thing. I literally sat down at every meal, prayed, ate, then made up my mind to make it back for the next one with my class. It sounds weird, but it worked for me. Some people break it down by days or weeks. I only had to go from chow to chow. You will have ample time to learn the things you need to learn if you follow the other things I said previously.
6: Work as a team- The goal is for most people to be a part of your wardroom, build those relationships. You may find yourself as 1 of 1 in your future shop. You will forge deep bonds and friendships that you will use later on. For my commissioning, I flew out my best friend (and first roommate) and my old platoon commander/OIC. I've known both for more than a decade and we have remained friends this while time. The people you meet can literally make or break your experience in the military.
There's probably other advice out there, but this helps me out.
