A hairdresser.
Then an ambassador, because at that young age I had this idea that all ambassadors lived in the pink houses in Regents Park. I'm actually coming back to this idea of being an ambassador now though, but for different reasons :P
Then, when I was about seven, I decided I wanted to be an author. Still working on that XD
Bizarrely, in the school that I attended for years 5 and 6 nearly all of the girls wanted to be marine biologists. I didn't even know what those were back then.
