This is what we love. Some one that seemingly look nothing like what they are good at, and yet is amazing at what they do. This girl seems like she's 12, but she plays the drums like she's in Red Hot Chilli Peppers or something. That is the kind of talent that we respect.
So no matter how you think you look like, or what you are interested in doing, don't let others stop you from doing it. practice and practice until you get it right. Just like how this girl is using her talent and going around the world busking.
