Perseverance refers to the determination to keep working toward a goal, even when obstacles or difficulties arise.
It is the mental strength and commitment to continue despite delays, failures, or discouragement.
While organisational and interpersonal skills are important, they do not specifically describe the act of pushing through challenges.
Taking initiative means starting things independently, but it does not guarantee consistent effort during hardship.
Perseverance is a key trait in personal and professional success, helping individuals reach their long-term goals.
Therefore, the correct answer is Perseverance.
