When you write you carry on a conversation with a vacuum. Perhaps you can put yourself into the other person’s position and carry on the conversation within your head. Otherwise, you write and just hope it works.
I write and then I revise, revise, revise trying to create something that will make sense to the other person. I enjoy the process - well most of the time. When I feel that it is becoming an obligation, then I am not going to do well. I write best when every minute is an expression of gratitude for the opportunity.
