It's a nonsense because, as we all know, there are brilliant 15-year-old readers and hopeless 50-year-old readers. All that categorisation is a matter of bookshop shelves rather than literary categories, I think.

What I look for when I see a piece of art for the first time is some kind of emotional, intellectual experience, that's a combination of both of those things and is informed by my knowledge and something new that I see the artist doing.

Set your sights high, the higher the better. Expect the most wonderful things to happen, not in the future but right now. Realize that nothing is too good. Allow absolutely nothing to hamper you or hold you up in any way.
