"Keep doing what you want to do and you'll get there in the end."
Whether that's Quentin Tarantino, working in a video rental shop writing scripts for True Romance & Reservoir Dogs on the side, or the thousands of garage bands with something real to say. I think we can all agree that hunger & desire are the key ingredients, its always the same story, just with different plot points (ta Olly).
I think the internet is an amazing realization of this philosophy. It crops up in much more bizarre ways than simply a movie director or a garage band, and here is one perfect example of that. This guy made this (fairly odd, but brilliant) video of a remix of Disney's Alice in Wonderland clips. He posted it up on the net, and eventually it got him doing the same thing, officially - for Pixar. I think that's true testament to the above quote.
Here's the Alice vid:
And here's the UP one:
