Disney went to Kansas City to make a living for its own ideal, but it failed repeatedly. Finally, he got a job painting for the church. But the salary is too low to rent a studio, so I have to borrow an abandoned garage as a temporary office. He works hard into the night in this garage full of gasoline every day. Every day when I turn off the lights and sleep, I can hear the squeaking of mice and the jumping on the floor. This little mouse appears again and again, not only at night. He never hurt it or even frightened it. Suffering gave him the sympathy of a great artist. In this way, a poor painter accepted a little mouse and shared a room with it, but he also felt that the abandoned garage was full of vitality. The little mouse is doing all kinds of sports and performing wonderful acrobatics on the floor. As the only audience, he gave it some bread crumbs. Gradually, they trusted each other and established friendship with each other. At first, the mouse was far away from him. Seeing that he didn't mean to hurt it, he got closer and closer. Finally, the mouse dared to climb the drawing board of his work and jump on it rhythmically. And he, however, will never drive it away, but silently enjoy the close affection with it.

Soon, Disney left Kansas City and was introduced to Hollywood to make an animal-themed cartoon. He remembered the mouse that climbed up his drawing board in the garage of Kansas City, and his inspiration shone brightly in that dark night. He got up quickly, turned on the light, set up an easel and immediately drew the outline of a mouse.

Mickey Mouse, the greatest animal cartoon image in history, was born in this ordinary way.
