The article, The Creativty Crisis talks a lot about creativity, and how most people think it is mostly used in art and music. However, the article claims
that when people do critical problem solving for problems that don't have a problem, they also use the creative side of their brain too.
The moment where your brain comes up with that "Aha!" moment is because of your creative side. You create ideas from past experiences
as well as things you already know and combine them to make new ideas, which you then test to see if it is a good idea.
While this may seem like a lot of work, it all happens in seconds.
