The ability to express one’s self without restraints or limitations.
Doing whatever you want to do is the freedom to move the goalposts whenever and wherever you want. That’s less about being creative with your resources and more about doing whatever the f**ck you want.
To my mind, creative freedom is the ability to do what you say you will do. Doing what you say you will do requires a range of skills to complete the task and an environment that affords you the opportunity.
That’s less about creative freedom and more about finding freedom with the constraints you find yourself under.
