We are the only witnesses to our work. We know how much, or how little, we put in.
Is there anything to lose if we put all that we have into our work?
Not everyone knows what that looks like. Leaving everything on the field has its costs. There is a manner of selfishness when one decides to become an artist of any kind. Time and attention are finite resources.
The insecurity of the artist stems not from the final quality of the work, but from the knowledge of the process.
What more could have been done?
It does not matter what else could have been done. What is there, left on the page, is the reality of process. It will never look the way we think it should.
It is what it is.
The process is the process. All it demands is a witness.
