You need a stubborn belief in an idea in order to see it realised.

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.

I imported the first Mac into England in 1984; you know, the beige box. I imported what I think were the first four that came into England. I never opened the instruction manual. That was the best thing about it.

If you can't be unconventional, be obtuse. Be deliberately obtuse, because there are 5 billion people out there thinking in train tracks, and thinking what they have been taught to think.

What I've learned from running is that the time to push hard is when you're hurting like crazy and you want to give up. Success is often just around the corner.

I want entrepreneurs to be engineers and scientists and designers; they don't necessarily have to be Internet entrepreneurs or retail entrepreneurs.

A lot of people give up when the world seems to be against them, but that's the point when you should push a little harder. I use the analogy of running a race. It seems as though you can’t carry on, but if you just get through the pain barrier, you'll see the end and be okay. Often, just around the corner is where the solution will happen.
