Keep on pushing towards your goal and trying to better yourself. Be keen and enthusiastic.

I have served 16 years in the Army now. I have lots of experience gained though courses, exercises, operations and life. But, there is always something new. Something I've never done before. A new system, weapon, theory or problem. You can always learn something new, or improve something old. Don't be afraid to ask for help and always seek feed back. But remember feedback will not always be positive.
