This is one of Robert Lowell's answers given during an interview:
"Can I get you back to Harvard for a minute? Is it true you tried out for the Harvard Advocate, did all the dirty work for your candidacy, and then were turned down?"
I nailed a carpet down. I forget who the editor was then, but he was a man who wrote on Frost. At that time people who wrote on Frost were quite different from the ones who write on him now; they tended to be conservative, out of touch. I wasn’t a very good writer then, perhaps I should have been turned down. I was trying to write like William Carlos Williams, very simple, free verse, imagistic poems. I had a little group I was very proud of which was set up in galleys; when I left Harvard it was turned down.
Can you explain what "I nailed a carpet down" means?
