Walt Disney is one of my favorite titans of the 20th century because he was a dude that had to keep plugging away to find success in life.
Did he have the creative control of some of his early animations and characters before Mickey Mouse stolen away from him? Check.
Did he spend much of his early life being mocked by his peers (and even his own father) for being a doodler and painter instead of following the social expectations of what constituted “normal” for a young boy and adolescent? Check.
