There are a few people who are so inspiring, that no mater how many times you hear their story, you never get tired of it. Walt Disney is one of those for me, and as many times as I hear his story, I always learn something new, some interesting story I'd not heard.
Despite the odds of life against him from an early age he was a man who never gave up, never stopped dreaming, and never stopped planning. Even his final hours were spent pointing to various parts on the ceiling, telling his brother just how he wanted EPCOT laid out. He never wasted his time, stopped working or reaching for his goals. Pluck, determination and imagination were his guides, just like it is for the characters in his films and perhaps that's what draws us over and over to these beloved stories, no matter how old they, or we are.
If you've never read a Walt Disney biography, I encourage you to, but if you have a few minutes to spare, watch this short film about Walt, narrated by Julie Andrews, that was played in Hollywood Studios at One Man's Dream. I've always found it inspiring, and hope it gets brought back to the parks one day.
