I'm now pumping saline, insulin next Friday

I am now pumping with a Minimed 522 with Saline. I will start with insulin (humalog) next Friday. It is SOOOO cool, let me just tell you. I keep pushing buttons as that is my "homework." I keep bolusing. I change my first site on Tuesday night (or late afternoon). I feel like this has all happened SO fast in a way so just....PLEASE GIVE ME SOME ADVICE OR WORDS OF LUCK AND/OR WISDOM. Thank you!
