Starting with the end in mind is crucial for success, as exemplified by Walt Disney’s creation of Disneyland. Disney’s obsession with miniature trains and his vision for a three-dimensional storytelling experience led him to meticulously plan every detail of Disneyland, treating it as a movie set rather than a construction project. This mindset of visualization and attention to detail resulted in a massive success, with Disneyland attracting millions of visitors since its opening.
