Officers, what is the best advice you gave an NCO?

When the time is available give your subordinates your rationale for why you made the decision that you made. It will help you in multiple ways. First, if someone understands when there is time, they will be more inclined to act with decisive initiative when you need them to and can't give the explanation. Second, it allows you to grow leaders because you show them how you made the decision and in the leader development job that we are in this should be a top priority.

You're in a unique position to train your future leadership. Remember that your new Lieutenant may be your son or daughter's Battalion Commander some day. Use this time to develop a leader you would want both you and your child to follow.

Set long term (>5yr) and short term goals to include professional development for your next career advancement maybe even a more attractive MOS for advancement. Those goals should include education, there are so many opportunities in the current force to get a higher education, (TA, program, formal schools cross credit, ect...) Keep working on it a little at a time and before you know it you will have a degree. Keep focused on your goals and do not let daily setbacks impact the big picture.
