The lull
From PickiPedia: A knowledge base of bluegrass, old time, and other traditional and public domain music
Your building - doing the thing.
And it's euphoria while it's novel; your fanbase swells quickly, your offering gets better and tighter.
But then it plateaus. The need for the hard work sets in - hard work done in relative quiet, like nobody notices and nobody cares.
But you gotta work through it. Almost everybody who is making the things you love to see and hear is going it because they worked through the lull.
