To those starting off at C5:
Learn everything you can while you are there. The dash is a lot of fun. The best advice I can give is this: after your first 100hrs RE READ the BLUE BOOK. The whole thing. What is written will make a lot more sense after you have flown. Also remember this: you ARE a captain in training. The best way to fulfill that statement is to remember that you are there to back up the CA. Make decisions in your head but remember that you are there to make the CAs job easier.
That is all!
