There will always come a moment when the joy of discovering a new artistic medium (I.E, writing) is eclipsed by the fear of not being good enough.
The amount of courage required for a task does not necessarily equate to an equal amount of compensation, success, or satisfaction.
You are right to be afraid of the writing life. It is lonely and often without prestige. The amount of time and effort put into improving your writing or creating a work of writing is rarely rewarded with a satisfactory amount of praise or money. But at the same time, if you’re a writer and you’re reading this, this probably isn’t a deterrent to you. You probably understand that the reward of the writing life isn’t in the reward, it’s in the thing itself. The reward is in the moments alone when the words flow outward and inward, connecting you to the entire universe.
