Today I was at a third hospital and people say things like I can't believe you remember from place to place what you need to do. The good news is anesthesia is anesthesia. Knowing where everything is even at a place you've worked for a year has a bit of a relativity factor. Meaning you get used to a place fairly quickly and if you get a halfway decent OR crew, anesthesia tech and are surrounded by decent people... it's probably going to be ok.
Now, Fun. Seriously, you have to go to work having fun! Plan each day to be exciting and happy. If you drag people down everyday and you are around people stressed and unhappy. Where will your job satisfaction be?
You have to have fun on the weekends, after work, and plan vacay!!! Life isn't just work. What you do outside of work leads to your whole self health. When I get off work I'm going to....
If your friend said when I get off work I'm going to take my daughter out for a walk along the river, see the urban culture of a melting pot of people at a skatepark to skulling for their college crew teams, then shower and have a relaxing corona by the pool. Would you think they were negative about the city or bored? If you are on an assignment you have to be the person that makes your afterwork and weekend plans. You have to be the friend that says hey let's go to Atlantic City.
Every place is what you make of it and it's important to keep yourself and others excited about what you do. That first plan was my night tonight. It cost 2$ for the beer and otherwise it was a free nights entertainment. Your colleagues, nurses, techs don't need to know when you spend $1000 on a trip but they should hear how excited you are about what's happening in their backyard. It also leads to your overall satisfaction by not becoming TV bound or complacent.
Best of luck and add some fun to your plan!
