Walt Disney is known for many things: being a pioneer of animated films, creating beloved cartoon characters such as Mickey Mouse, and opening one of the best-known theme parks in the world — to name just a few. While it’s clear that none of these things could have been achieved by someone who rested on their laurels, it’s often understated just how much tenacity Disney had. Despite humble beginnings and several failures along the way, the artist and impresario rarely rested, and even worked on building Walt Disney World right up until his death in 1966, proving that the secret to success is to indeed stop talking, and start doing.
