just started!

I just got hired at my local Dutch, I start training on Wednesday, should I be worried? I know the like pressure is a lot, I worked a month at my local waffle house so I know what pressure feels like but I'm still worried about feeling overwhelmed or being too slow at making things or not being able to remember all the recipes and stuff, besides constantly going through DBU, is there anything else any other fellow broistas can tell me to help make this job a successful one??
