Work placement poster

Hi! I'm about to start my placement in a child care centre, I went to my induction yesterday and was asked to print out 2 copies of a poster that will hang on the door to where I'm working and one at the front desk. I was also told to write a small introduction in it.

I was looking at the one on this site which says,

Hi everyone - my name is Cassie and Ill be here for work placement over the next month. I really enjoy working with children and this is a great chance for me to do what I love! I have just spent the last couple of months volunteering at a school in South Africa and have lots of ideas to implement here!

I dont know what I should and shouldn't write! I have 0 experience with working with children and havent been anywhere but Australia. I only have pets and I've never worked before. What do I talk about then?
