How do you describe a person who always compare with others?

A person who constantly compares themselves to others may be described as insecure or competitive, often seeking validation through external benchmarks. This habit can stem from low self-esteem or a desire for approval, leading them to measure their worth against the achievements and qualities of others. Such comparisons can hinder personal growth and foster feelings of inadequacy or envy. Ultimately, this behavior can create a cycle of dissatisfaction and discontent.
