A Clergyman's Daughter - George Orwell

'Those things don't really matter. I mean, things like having no money and not having enough to eat. Even when you're practically starving−it doesn't change anything inside you.'
'Doesn't it? I'll take your word for it. I should be very sorry to try.'

'Oh, well, it's beastly while it's happening, of course; but it doesn't make any real difference; it's the things that happen inside you that matter.'
'Meaning?' said Mr Warburton.

'Oh−things change in your mind. And then the whole world changes, because you look at it differently.'
