I found this article earlier today, that I think, highlights some major aspects that all future 2LTs/Ensigns should consider by the time they commission and make it to their unit. What I wish I Knew: From Cadet to Lieutenant Although this article is geared towards 2LTs in the Army - it's equally applicable to all service branches. I personally think out of all those listed, number 2 is the most important to always be aware of. And to all of the incoming high school seniors and future seniors, I hope this article serves as an eye-opener to see what it truly means to be an O-1. I came in to ROTC knowing very little of ideas surrounding leadership and the responsibilities associated with being a 2LT - and yet already it feels like I've learned a lot, in the little time I've been in ROTC. For you are about to embark on a journey filled with some wonderful experiences and lifelong friendships; this is just the beginning! So take the time, and learn from all the things you do. Find out what works and doesn't work to make yourself a more successful person; learn from your mistakes. College is about figuring out what works and doesn't works, so you can perfect them then, rather than messing it up in the "real world."
