If I were to try and find a unifying emotion that kept me calm and focused while I was dancing or writing or solving a math problem, I think the one unifying thing about all those that keeps my interest is creativity.
Sentiment: NEGATIVE
I always knew that I was tremendously creative. I recited love poems, I wrote stories and I got excellent grades in every subject, except for maths.
I consider creativity to be a more non-rational, subconscious thing. You have a relationship to your creativity - you can feed it with content, with some rational prodding and sleep and things like that, but the mechanisms by which your creativity work are largely unknown.
