What is the first paragraph of the chapter saying about how Janie handles her "emotional disturbances"?

From the text:

The years took all the fight out of Janie’s face. For a while she thought it was gone from her soul. No matter what Jody did, she said nothing. She had learned how to talk some and leave some. She was a rut in the road. Plenty of life beneath the surface but it was kept beaten down by the wheels. Sometimes she stuck out into the future, imagining her life different from what it was. But mostly she lived between her hat and her heels, with her emotional disturbances like shade patterns in the woods—come and gone with the sun. She got nothing from Jody except what money could buy, and she was giving away what she didn’t value.

Janie had learned how to pick and choose her fights. She preferred silence to confrontation.
