Just accepted my first job in the SICU as a new grad RN. Any tips for success?

As the title suggests, I accepted a new grad RN position in a trauma level 1 surgical ICU. It was my first choice so I am very excited to start in a few months! (after taking the NCLEX of course).

Prior to nursing school, I had very little healthcare experience. Are there any ICU nurses with recommendations for how to acclimate to the ICU environment and become knowledgeable/confident? I know there are a lot of ICU cheat sheets out there for pharm, etc. I'm open to that if you have one in mind and think it's worth it.

What was starting in the ICU like for you? Do you recommend I do anything to prepare over the next few months before I start working?
