Here goes three declarations of Disney that stand, respectively, for courage, single mindedness and dignity: the three aspects of integrity.
"I traded security for self-respect."
"When you believe in something, believe it all the way"
"When I do something is because I want to do it better"
(The first one is revealed, thanks to Didier Ghez, in the Newspaper articles of 1941 he posted in his blog "Disney History")
