There are a number of quotes that writers love to site that are along the lines of “writers must write.” Here’s one:
“A musician must make music, an artist must paint, a poet must write if he is ultimately to be at peace with himself. What one can be, one must be.” –Abraham Maslow.
I find these to be some of the most destructive quotes and thoughts that any writer can have. If you want to give up, to quit, take quotes like these to heart. If you want to write, to finish, to publish, you must put these thoughts aside and have a more reasonable view on the craft of writing.
