I gained a humility that I needed in order to balance my audacity. I wanted to find the smartest people who would disagree with me to try to understand their perspective or to have them stress test my perspective. I wanted to make an idea meritocracy. In other words, not an autocracy in which I would lead and others would follow and not a democracy in which everybody's points of view were equally valued, but I wanted to have an idea meritocracy in which the best ideas would win out.

I've never set out to be a spokesperson for women's equality. My experience of working with Amelie Mauresmo gave me a small insight into attitudes to women in sport and, because it was unusual for a male tennis player to work with a female coach, I am often asked about that. Working with Amelie was, for me, because she was the right person for the job, and not a question of her sex at all. However, it became clear to me that she wasn't always treated the same as men in similar jobs, and so I felt I had to speak out about that.

One thing that I went through and I was able to understand is: It's OK to not be OK. Right? Like nobody's perfect.

Yeah, I remember exactly that—I was in San Francisco, playing at a beautiful venue, and the siren of an ambulance came through, and it fit so well with the song that I started to play more to draw it out. I like to play in more noisy places so that I can take advantage of all the sounds helping me to build new things. But the one I remember the most is that siren in that venue. Sometimes I’ll play in venues where they’ll have coffee machines or milkshake machines—all these noises that I hated maybe five years ago—I love them now.

Day one of my first job out of college, my boss found out that I didn't know how to enter data into Lotus 1-2-3. That's a spreadsheet—ask your parents. His mouth dropped open and he said, ‘I can't believe you got this job without knowing that”—and then walked out of the room. I went home convinced that I was going to be fired. I thought I was terrible at everything… but it turns out I was only terrible at spreadsheets.
