If you want to do something different, you’re going to come up against a lot of naysayers.

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

In the past, the U.K. got away with selling things that weren't unusual. Now it's no use trying to export without having something that's unusual and better.

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

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.
