['I am starting a new job tomorrow and I am so nervous. I home that it goes well.', "Congratulations and I'm sure you will do fine.  Do you think you will enjoy doing it?", 'I think so, but I never done a job like this before so I hope do well.']
It'll be a good experience at the very least, good luck!
I'm really nervous about going to work tomorrow. It is my first day.
