You are the only one who can practice your skills

You are not in control of the process by which your art is made. But you are the only one who can practice your skills so that you have the flexibility to track with the process. This is your job-to master your craft. For me it’s learning how to make sentences work, how to shape scenes, how to flesh out characters. That’s my work. That’s what I practice. This skill is my contribution to the creative work.
