When an individual demonstrates persistence, they exhibit determination and resilience, often maintaining their efforts even when the situation becomes challenging or when they encounter setbacks.

Stopping immediately indicates a lack of commitment, giving up easily suggests a willingness to abandon efforts at the first sign of challenge, and following others' opinions implies a lack of individual initiative and determination. Therefore, the aspect of continuing despite difficulty is what defines persistence.
