Congrats, good luck and thanks for your future service.
Advice;
Keep your hair in spec.
Keep your shoes black.
Keep your uniform pressed.
Keep your face shaved.
Say sir/ma'am/chief at the end of every sentence.
Do those simple military things, and no one will want to make an example out of you. If you have issues elsewhere, they will be more willing to help you if you can nail down basic military requirements.
