The one difference I have noted is that it's made me more tender to my students and to young people particularly. It's made me mellower. I began to have a different perspective, because I may not be around much longer to be hassled by life's pressures.

"Time" does not mean "occasion."

I'm in my 60s, and a cancer scare just makes you more aware of mortality.

I was walking every morning, and I'd take my iPod and paper and pen. As I walked, I wrote a poem, and then I'd come home - and sometimes it's legible, sometimes not - I typed the poem up. So I have a new, yet to be published, collection of poems now. It's called Walker's Alphabet, and among other things, it is about walking. My most recent collection of poems in 2010, incidentally, was titled WALKING backwards.

I'm nomadic. Even when I'm a visiting professor here at the City University of Hong Kong, in this campus flat, I'm constantly getting up, sitting down, picking this or that up. You can't do that and be a writer. You need to be able to sit still.

I look at my young students, and I no longer have the sense that, oh, I'm the authority and they have to meet a certain standard. It's like, oh, look at these young ones. They've got such a hard road in front of them. I don't envy them having life ahead of them.

In some ways it is absurd for me to assert, counter to evidence, that I have not been writing.
