When I see myself at 14 years old I can put my hands on my head and think: 'How could I have done that?' but at that time it had sense for me. You do the same when you're 20. And now, when you look at people who are 20 years old you ask yourself: 'Was I like that? Was I really like that?'
You hope that your teenage self would like and forgive your 50-year-old self.
My poor mum had a lot of problems with me around that time. I was young but I'd been working for years, so if she asked me to clean my room I'd say, 'You can't tell me what to do after I've worked a 12-hour day.' It gave me a power that no one that age should have.
