green ceiling
n.— «In Mexico, I painted, I read and then got the idea that I could be a writer.…Back home, I was going to face what I call the “green ceiling.” It was the attitude among the older generation of Irish that you shouldn’t aspire to anything too “artsy.” The question was always, “Who do you think you are?’ when the idea of being an artist came up.» —“Novelist Hamill still a reporter” by Bob Hoover Post-Gazette (Pittsburgh, Pennsylvania) June 10, 2007.
