Always be constantly improving.
“Whenever I go on a ride, I’m always thinking of what’s wrong with the thing and how it can be improved”. -Walt Disney
Walt believed in the future. He insisted that Steamboat Willie have the sound synced and recorded, unheard of for a cartoon at that time. Before Snow White, there was no such thing as a feature length animated film. After it became a huge success and literally changed the film industry, it led to the success of several more beloved Disney classics like Cinderella, Alice in Wonderland and Fantasia. Walt Disney could have rested on his laurels, but that wasn’t his style. Instead, he completely switched gears and set out to build an amusement park where parents and children could have fun together. Once Disneyland opened, Walt would walk around the park, personally testing all the rides, noticing if anything was out of place and asking the guests their opinions. If he noticed something was wrong, he would personally see that it was fixed. As his animators could attest, good enough was never good enough for Walt Disney.
