It took me till I was 31 to know what I wanted to be when I grew up. However when I was in high school teaching was on the rader for a little bit but once I left school Uni wasn't even on my mind. It wasn't till the kids started school that I realised where my passion was and I am 100% certain I want to be a primary school teacher. And I'm just loving it. It's been very rewarding for me to decide to start uni at my age.
