On changing direction.......

Dan Harmon posts on the necessity of being bad writers if we
are seeking to become good writers.  Just write.  Excerpt here:

"A rat would never get through a maze if it thought a rat’s job was to know which way to go. The dead end is not the problem in need of solving, the hunger is, and the way to solve the hunger, the way to get the cheese, is to respect a wall for a wall. To receive each obstruction as a message from the laboratory: 'You’re not going this way. Period. Change direction.'"
