First job/First day of work, 5pm to 1am.. Nervous..?

Normal to be nervous right? Never had a job before, I'm 19, they are starting me at 11 a hour, and starting me with pallet wrapping, then stocking and then forklift stocking or so. I'm nervous.. They are gonna teach me wtf I need to do and stuff right? Is it easy? It's an industrial warehouse.
