A Curious Cat Question

Here's something said by editor Sean Wallace:

Never second-guess yourself or your submissions. Leave it to the editor to make a judgement call. Your job is just to write the best story possible, and then to send it off (to the proper market, mind you). By basically handicapping yourself by putting up roadblocks, like assuming a market isn't right, or that the editors hate your work, or that the competition for slots is simply too high, you're doing the worst possible thing, to your work and yourself.

More to the point, I got a lot of feedback from some writers who said they couldn't write secondary world fantasy. I had to wonder though: why? Shouldn't we-- as writers of the imagination-- be able to produce ideas that transcend what we usually write?

I mean, if we fail because we couldn't write a particular type of story-- whether it's the urban romance story or the gothic erotica story or the science-fiction comedy story or the secondary world fantasy story-- then we fail. But we might as well fail big, you know?

What do you think?
