Being someone who is in his early thirties and someone who has been working in the creative field since college I feel I can offer up some valuable insights. In my opinion, creativity is 40% passion, 30% execution, and 30% failure. What does this mean? Let me explain. Passion is what drives us, it's why we get up in the morning. It's the itch that needs to be scratched. We all have it and it's our choice to pursue it. A passion that's not pursued is simply a dream.
That's where execution comes in. Execution is the act of pursuing your passion. Educating yourself, gaining experience, laughing in the faces of the people who doubt your abilities, facing the fear and societal pressure that hinder us from pursuing our passions. It's not easy. In fact, it's extremely difficult.
Failure is certainly a big part of this trifecta. When pursuing your passion, you will fail, and success comes when you fail time and time again and continue to push forward. With each failure you learn something and each time you learn something you improve upon yourself.
I found this video essay on the creative process extremely interesting and I feel that it does a good job in helping to illustrate my point.
