I ran across something Richard Sullivan shared with his creative writing students at the University of Notre Dame way back when. He said that the two most important physical dimensions of the writing profession are time and space.
“Write every single day at the same time and in the very same place.”
“Whether you have anything to say or not, go there and sit and do nothing, if necessary, until the very act of sitting there at your writer’s time in your writer’s place releases the writing energy in you and begins to affect you automatically.”
Sounds like sound wisdom to me.
