Do you remember Oswald the Lucky Rabbit? Not everyone does. He was one of Walt Disney and Ub Iwerks' first successful cartoon characters when Disney first became an animator. Walt and Ub, along with a team of soon-to-be big animators, were creating Oswald's cartoon series, produced by Charles Mintz, for Universal Studios. Walt negotiated with Mintz for a better budget since Oswald was doing so well, but was instead threatened with a pay cut which he would not accept. Because Disney would not agree to the cut, rights to Oswald remained with Mintz and the studio. Disney also lost most of his team of animators, except for Ub Iwerks.
After suffering such a big loss, Disney could have given up, turned in his paintbrush and decided animation wasn't for him. But he didn't. To replace Oswald, Disney created what would become the most famous mouse in history.
What can we learn from the story of Oswald the Lucky Rabbit? When creative people face setbacks, they overcome with even more creativity. Disney continued to top himself, creating more and more outstanding work in his field throughout his life. What could've ended with a rabbit began with a Mouse.
Don't lose heart when setbacks happen. What looks like the worst could turn out to be the best thing that's ever happened to your career.
