It is no good getting furious if you get stuck. What I do is keep thinking about the problem but work on something else. Sometimes it is years before I see the way forward. In the case of information loss and black holes, it was 29 years.
Anytime something starts to feel like a popularity contest or not about the music, I'd rather just not be involved. I'm not a big high-fiver. That really gets to people around me when we have a No. 1 or something big happen. I'm not a big, 'Let's go have a party about it!'
