I had some years of definite frustration. Auditioning and not working as much as I would have liked to, or working and being paid a pittance, and sort of scrounging by in New York and sleeping on a chair that folded out into a bed.
Even if I couldn't get my early novels published, I could still write. I went into newspapers, where I got paid to write every day. If there's a better school for would-be novelists, I don't know what it is.
