Jewmentum
(n.) -- the inner confidence of a Jewish person to persevere against all odds and come out with a successful outcome, no matter what the endeavor is, big or small.
"Oh, I know the odds are against me, but I really want to try my hand at writing a novel, and I'm hoping my Jewmentum will carry me through to the end. It's a dream I have had since high school, to be a novelist!"
