Anyone developing new products and new technology needs one characteristic above all else: hope.

Far too few designers put any thought into usability, ending up with a great product that's completely inaccessible.

I've fought court battles over my inventions before.

Successes teach you nothing. Failures teach you everything. Making mistakes is the most important thing you can do.

We’re taught to do things the right way. But if you want to discover something that other people haven’t, you need to do things the wrong way. Initiate a failure by doing something that’s very silly, unthinkable, naughty, dangerous. Watching why that fails can take you on a completely different path. It’s exciting, actually. To me, solving problems is a bit like a drug. You’re on it, and you can’t get off.

The one size fits all approach of standardized testing is convenient but lazy.

Success is made of 99% failure.
