what is the main difference between a personal characteristic and a skill?

The main difference between a personal characteristic and a skill is that personal characteristics are inherent qualities related to a person's personality and traits, while skills are abilities that are learned, acquired, and developed through training, practice, and experience. Personal characteristics tend to be stable and enduring over time, whereas skills can evolve, improve, or be replaced depending on life circumstances. Characteristics reflect who a person is innately, whereas skills reflect what a person can do based on what they have learned.
