"If your goal is to make pretty pictures, then every time a drawing does not work out the way you wanted, you will be disappointed and then less likely to pick up your pencil the next time. Instead, make it your goal to learn to observe more closely and to remember what you have seen. With these goals, every drawing will be a success and you will keep drawing." 

- John Muir Laws

"As practice makes perfect I cannot but make progress; 

each drawing one makes, each study one paints, is a step forward." - Van Gogh

"What would life be like if we had no courage to attempt anything?" - Van Gogh

"Every drawing is practice for the next one." - John Muir Laws
