I think you can learn the answer by listening to those stories. For each woman it's a bit different, but the things that have come through that I've heard are a hope that it is possible that they can succeed, actually having people who believe in them, and community support. It's those constellations, and people will often say that they had a moment when they thought, “Aha--it is possible that I can do it”.
That's another research project, to actually gather those stories that tell us about the moment. It will be a realization. It might take a while for them to effect it. It's almost like a teeter-totter; the motivation turns, and things align for them so that they can actually turn it around, but they have to have that hope.
