1974, w, w:Zen and the Art of Motorcycle Maintenance, A person filled with gumption doesn't sit around dissipating and stewing about things. He's at the front of the train of his own awareness, watching to see what's up the track and meeting it when it comes. That's gumption.

1936Margaret Mitchell, ("Gumption" was used as one of Scarlett O'Hara's defining personality traits.) "What qualities are in those who fight their way through triumphantly that are lacking in those that go under? I only know that survivors used to call that quality 'gumption.' So I wrote about people who had gumption and people who didn't."
