here are my fav quotes from it, which are mostly Robert Henri quotes with some Walt Disney commentary added

((I changed the quotes a bit, to fit a more modern sense of gender neutral))

“…educate yourself, do not let me educate you”

“…students become confused by honest admiration for one school of painting, mixed with recognition of the success & popularity of another style. Along with advice to follow a still different approach. Frequently a student will ask which one they should imitate”…“don’t imitate anyone”

“One of the great difficulties of an art student is to decide between their own natural impressions, and what they think should be their impressions”

“Go forward with what you have to say, expressing things as you see them”

“The great painter has something to say; they do not paint people, landscapes, or furniture, but an idea”
