Here's to the crazy ones, the misfits, the rebels, the troublemakers, the round pegs in the square holes... the ones who see things differently -- they're not fond of rules... You can quote them, disagree with them, glorify or vilify them, but the only thing you can't do is ignore them because they change things... they push the human race forward, and while some may see them as the crazy ones, we see genius, because the ones who are crazy enough to think that they can change the world, are the ones who do. - Rob Siltanen
This Rob Siltanen quote is always one that I find super endearing. It's alright to be different and question the foundations of the things, because those who dare and are brave enough to do that are also the ones that change the world the most. It was also part of Apple's think different marketing campaign (perhaps what most of us remember it for).
