Back in 2015, when he was promoting his novel Nora Webster, Colm Tóibín talked about the advantages of growing older, from a personal standpoint:
That’s one of the things you learn as you grow older. That if you don’t like someone, you never like them, and they never like you. It’s not something you grow out of, no.
While this might suggest a somewhat relaxed worldview, Tóibín in fact approaches his work like he’s on a clock:
I mean, well, there are writers who do drafts, knowing there will be later drafts, and that works for them, but I don’t do that. It doesn’t mean that there won’t be later drafts, but I write as though I will never get another chance.
This might not work for some who prefer to write long then cut. But it’s hard to argue with the practicality of putting it all down as you intended in one blaze and then moving on. Life is short. Books take a long time.
