Thinking about applying to CTICU... Need a confidence boost

I have been working on a medical step-down unit for a little over a year, and just saw a position open up on our CTICU. My original plan was to wait at least another 4 months to start looking (mostly out of courtesy to my current manager), but these positions don't open up frequently and I feel that I should at least try applying.

The position requirements are at least one year of critical care experience. My unit is officially considered a critical care unit, and while we don't titrate drips, I do have quite a bit of experience with vented patients. I know..... I don't know everything, but I'm sharp, hardworking, and intellectually curious. Plus, my learning curve on my unit has slowed down so much, that I don't think another 4-8 months would give me that much more, aside from an extra code or two. I have become bored on my unit, and while I do like it, Im itching to move on to my goal of working in an ICU. I feel that I know the basics, and I can perfect my critical training in a faster paced learning environment.

In my head, my worst case scenario is that I won't even get considered, so need a confidence boost or valuable advice and insight from CTICU nurses on the subject. Do I have a shot?
