I predict that Vianne's present-day self will start being less pessimistic and upset about her current life and start being appreciative of the life she has.
I think this because she in the present day, she is an older woman who has survived the war, and is now telling her story to her son, who is incredibly curious (and doesn't remember or know about certain details like her abusive relationship).
I'm making this prediction because of my prior knowledge about when people reflect, much like the "bench scene" in the movie Forrest Gump. Forrest tells his story to strangers and is able to reflect that "life is like a box a chocolates: you never know what you're gonna get." Even though he went through hard times, he was able to reflect (positively) about how it's up to chance.
