Creativity is born from interacting with as many different elements as possible around you.
One of the tricks is to not limit yourself to just listen or watch content you always love. Open up yourself to explore more and embrace new contents.
Question what you observe and what you see. Constantly fight the reason to why it is done the way it is.
It is good growth to your creative brain to challenge the state of how certain things are done after observation to think about how else could it have been done.
