This is the question I want everyone to ask yourself every single day when you come up with something you feel that needs to be done: if not now, then when? And if not me, then who?

I have a company that does design and animation, so obviously graffiti is definitely an intricate part of what we admire and respect in the art world.

We've created a device that has absolutely no limitations. There's no insurance company that can say 'no.' There's no hospital that can say 'no.' Anybody who's paralyzed now has access to draw or communicate using only their eyes.

I actually feel most at home when I find people who make me feel really dumb, who are brilliant at their particular things. And then I gather these people, put them in a room and watch incredible things come out of it.

Jump and the net will appear.

Surround yourself with people who make you feel stupid.

The reality, I believe, is that all change starts small. The big picture is just too unwieldy, too incomprehensible and seemingly immovable. But give us something individual, quantifiable and personalize-able and, suddenly, our perspective shifts to the one.
