When I was in my 30s, I was at the end of a long-term relationship and going through a very hard time. I'd had about 15 different addresses and a series of relationships. I thought, 'It's time to have a look at yourself.'

I left school at 16 but I wish I'd gone to university - I think I would have studied English literature. I had a knack for that. But I don't think you have the kind of wisdom at 16 to make that decision.
