“‎If you regard evidence as a constraint and seek to free yourself, you sell yourself into the chains of your whims. For you cannot make a true map of a city by sitting in your bedroom with your eyes shut and drawing lines upon paper according to impulse.”

“Above all, be true to yourself, and if you cannot put your heart in it, take yourself out of it.”

“You cannot make yourself feel something you do not feel, but you can make yourself do right in spite of your feelings.”

“Art is limitation; the essence of every picture is the frame. If you draw a giraffe, you must draw him with a long neck. If in your bold creative way you hold yourself free to draw a giraffe with a short neck, you will really find that you are not free to draw a giraffe.”

“There is no reason why you should be bored when you can be otherwise. But if you find yourself sitting in the hedgerow with nothing but weeds, there is no reason for shutting your eyes and seeing nothing, instead of finding what beauty you may in the weeds. To put it cynically, life is too short to waste it in drawing blanks. Therefore, it is up to you to find as many pictures to put on your blank pages as possible.”

“Let no-one define how you see yourself...save God alone. See yourself through His eyes and His strength, and you'll see who you can be despite being who you are. But see yourself through your own eyes, and you'll be left to question, and to doubt, subject to the whims and wishes of others who will not have your best at heart.”
