Creativity requires you to be courageous. In order to do something creative, you must go beyond the limits of your comfort zone. You have to be brave. You need to step into new fields. You have to do what is not safe and familiar to you. That is where true creativity is born.
If you stay in the zones of what you have done before, you will never be able to step into realms of new creations. This will keep hindering your creative process and you will get stuck in a rut. Sometimes, creativity requires you to be vulnerable and being vulnerable is often very difficult. That is why being creative takes a lot of courage.
