As a CIC officer you will be required to play several roles. You will be spending quite a bit of time applying your training and doing the work of administering the cadet program and conducting training regardless of the section at your unit they put you into. Remember that you will often be the supervisor, and the instructor, so you need to offer constructive but honest evaluations of an individuals performance. You will also be a trainee and must be willing to accept the criticism of your peers, superiors, and subordinates from time to time as each offer a valuable perspective on how you do your job.
You will also often perform the role of a mentor, beyond simple skills. It has been my experience that over time the cadets do seem to "bond" with their officers and often will seek advice on dealing with the daily realities they face. Be honest, be concerned, and listen. Offer advice sparingly, but help your cadets make decisions for themselves. Always escalate issues in a timely fashion, and pay attention to what your cadets are asking from you.
"Socialize" when possible with your fellow officers, both CIC and from the Reg F and PRes, to establish a network of experience and ensure you learn from what they can tell you. Draw on your expereinces, and learn from those of others. Always remember that your beest advice will come from Snr NCO's because they have been there and done that (speaking largely of the PRes and RegF types not your senior cadets, but don't discount them either). Be respectful of others positions and it will eventually earn you their respect. Try and live the aims of the program (i.e. physical fitness, community involvelement, etc.) and your example will be clearer in the minds of your fellow officers and cadets, never ask them to do something you aren't perfectly willing to do yourself.
Beyond that, keep an open mind, and check your assumptions regularly. You'll figure it all out in time, there is no quick answer or quick fix.
