The motivation to write

With an imminent (as in tomorrow morning) deadline for a three act play (who'd join a writing group?) hanging over me I've been reading a biography of Spike Milligan. At one stage he was writing a new episode of The Goon Show every week for broadcast on the BBC. Now there's pressure, and what it can do for productivity! Mind you, it didn't do much for his mental health, so perhaps I don't want quite that much motivation!
