There are courses and books all talking about how good it is.
However, it also feeds into a narrative that is part of everything in the so-called developed world. How all our energy should be funnelled into being productive in the economy.
Creativity is a code for enterprise, being emtrepreneurial - therefore generating more income and fulfilling ourselves as productive units.
Creativity lead into discussions of inspirational people, often citing Steve Jobs, Walt Disney and Thomas Edison. Clever people who managed to come up with money-making ideas, often built on the work of others.
Though they may have been creative, their goals were business success not just some self-expression.
So, be creative, do express yourself but do it for the right reasons, not for money.
