Writing is a muscle, a superpower and a way of translating the world into smaller bites for other people to digest. This is not for the faint! But be brave in your wording, steadfast in your creative intent, and don’t be afraid of critics.
There is no need for you as a writer to ask permission to create. You cannot be subject to this! You must have the wherewithal to work in the midst of doubt, or doubt in the midst of work. Permission is one of those thing which rely on just the freedom of the self. Are you able to release the thoughts of other people as it relates to what you want to create–so you can create?
If you cannot, you will ever wait for someone to grant you the freedom you need to have for yourself–and be dependent on it.
