Answer:
The principle of self-reliance
Step-by-step explanation:
This principle entails a person's drive and motivation to get things done by their own terms and for themselves. People with this principle have the ability to trust and depend on themselves to meet their own needs. Jo's statement clearly specifies that she wants to be "perfectly independent," meaning she does not want to rely on others, and she also mentions how she would rather do everything for herself, meaning she feels capable enough to do things alone and not ask for help. Her statement truly exemplifies the principle of self-reliance.
