The authority in your head tells you not to do something because someone will tell you off. It tells you not to take risks and follow the safe path because you will fit in. It tells you to always ask for permission. It tells you that your bosses are right and you should maintain status quo. It tells you not to speak up when something is wrong, because it is the way the world works.
There is an authority in your head, that is serving as a proxy to all the other authorities in the world around you.
Shut that thing off. Ignore it. Make ruckus. Create art. Don’t give a damn to that voice. Because beneath that voice, there is another one, which is quieter. That is the voice tells you to hope, dream and change the world. Your goal should be to make that the primary voice in your head.
