The discipline of writing might be the most important part of the entire endeavor.
For nobody got better, at anything – ever – by not practicing.
You search high and low defining the type of person you want to be, and then you act in that way, regardless of the outcome.
An example for me here is in telling the truth.
See, I try to be honest (not rude) regardless of the consequences. Often, I do not want to tell the truth. But I do it anyway. Because that is the kind of person I want to be.
I write every day, regardless of the results too. And believe me, I frequently do not feel inspired to do so. But I do it anyway because I want to be a person who writes.
A disciplined approach to writing is an important part of the process. I write every morning, rain or shine, summer or winter, for no more than four and a half hours. I have learned that if I go beyond four and a half hours, my writing shows fatigue. For me, writing is a long distance race, not a sprint, so endurance is a quality I cultivate. This puts me at odds with the popular notion that the artist is supposed to be a tormented genius—a Strindberg, Nietzsche, or Ezra Pound who goes mad for his art.
