I studied neuroscience at the cellular level, so I was looking at learning and memory in the visual cortex of rats. Neuroscience mainly exposed me to a way of thinking - about experimentation, about what you believe to be true and how you could prove it - and how to approach things in a methodical manner.

Most of us yearn for really intimate, healthy, in-person relationships. People have a deep desire to be understood, to be told that it's OK, that you're not isolated and broken, that this is part of the human challenge, and that there is hope. The capacity for online interactions to do that is powerful.

Let me think about the people who I care about the most, and how when they fail or disappoint me... I still love them, I still give them chances, and I still see the best in them. Let me extend that generosity to myself.

On street corners everywhere, people are looking at their cell phones, and it's easy to dismiss this as some sort of bad trend in human culture. But the truth is life is being lived there.

When you've got money to spend, it's very easy to buy someone worth £50m rather than say, 'I'm going to play this 20-year-old English player.'

My first synthesizer was the VCS3. I got it in Bristol in the late Sixties, long before Pink Floyd used them. I had to sell an acoustic guitar and an old reel-to-reel tape recorder to raise the money. You can do fantastic things with modern computers, but you cannot use them in the same intuitive, spontaneous way you can a VCS3.
