(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!"
