Ohhh now this is easy for me to pick :)
I love to be creative and make Art, especially illustration style work. Be it for myself , a contest, an idea for a kids book to even just a simple doodle on paper. Art has and always will be my main creative output. Since I was a kid :) I've found inspiration all around me and turned it into my own visual interpretation.

The wonderful thing about art is it can take any form too :) so not just the 2d form like the images above but 3d modelling on a computer to physical sculpting with clay, heck even a sandy beach is perfect playground to express yourself :D It's something that I'm actively passing on to my kids too :-)
