I will be honest with you: writing is one of those arts that will only get better every time you use it. Every time you rely on it. Every time you trust it, and within it.
One of your deepest wins as a writer is to embrace that title! I am pressed to remember that a writer is two-fold:
A writer is something you are.
A writer is something you become.
It indeed feels like a complex thing, but it isn’t. Owning your title of writer is freeing–it really is. It allows you to embrace all that is complex about you, and bring that complexity to all that you would create.
Self-possession and self-realization are always wins.
