An artist must be passionately in love with her art. Obsessed or possessed ― go mad for what you believe in.
I love to write. But it has never gotten any easier to do and you can't expect it to if you keep trying for something better than you can do.
Every writer should know their target. Aim for the heart ~ hit that and all which follows is sheer ecstasy.
Good writing is true writing. If a man is making a story up it will be true in proportion to the amount of knowledge of life that he has and how conscientious he is, so that when he makes something up it is as it would truly be.
