Whenever I've been stuck on a project, it's always brought me solace to the return to books that moved me in the past. It's a nice way to get outside my own head; and it brings me back to one of the most important reasons I write at all: to bring some pleasure to readers, to make them think or feel.

Armchair poverty tourism has been around as long as authors have written about class. As an author, I have struggled myself with the nuances of writing about poverty without reducing any community to a catalog of its difficulties.

The global phenomenon of poverty tourism - or 'poorism' - has become increasingly popular during the past few years. Tourists pay to be guided through the favelas of Brazil and the shantytowns of South Africa. The recently opened Los Angeles Gang Tour carries visitors through battle-scarred territories of urban violence and deprivation.

Sometimes I do feel exposed. I have this kind of theory about different channels or levels of relaying experience - when I tell someone, one on one, in a personal context, about something that's happened to me - that has a very different valence, a different charge, than when/if I've said it in a public forum.

The publishing industry, unsurprisingly, is full of different people who love different things and express that love in different languages. Find the people, the editors and agents, with whom you share some language, and some sense of what makes literature worth reading.

I think of empathy as a set of cumulative effects, ideally - that it can be a force shaping your habits, shaping where you put your attention and then - if you're hard on yourself, in good ways - pushing you to translate that attention into action, on whatever scale.

Commonality doesn't inoculate against hurt.
