Her life is basically fine, which is arguably the problem. She has a job, she has a flat, she has lunch with her uncle once a week! She has a soft couch to watch tv on, a solid rotation of tasty-enough dinners, clever internet acquaintances and a reasonable percent of effective donation!
If she could reach greater heights of accomplishment—she would have to care about that more strongly than her life being fine and easy moment by moment. And she doesn't! She doesn't actually want many things in between her life being basically fine and everyone else in the world being basically fine. The ones she did have mostly being accomplished (pending final decision on whether 'woman' was a slight over-correction; but she's basically there either way) and—she doesn't see a good angle on everyone else's.
She's not actually ruminating on that. Right now she's going for a walk.
