Back then I was shy and socially awkward, and I could fly off the handle without knowing why. I didn’t realise I had ADHD, so I was bouncing off the walls one minute and crashing the next. I was creative, but often privately: the kind of precocious show-off who’d put on a magic show with my brother, doing silly card tricks, but if someone asked me to do something heartfelt, I’d freeze. Even now, at 44, I’m still terrified to play new songs for people – the words “Come on, Josh, play us a song!” at a party remain my worst nightmare.
