Abstract: Intrapersonal skills are integral to human lives. As applied in a management setting, intrapersonal skills are fundamental to leaders. Assessment on relationship between intrapersonal skills and leadership performance as well as relation to leaders’ profile can help management to prepare their millennial leader on develop their soft skills to be better leaders in the future. Based on big five theory on Intrapersonal Skills of Leaders, the five elements (conscientiousness, agreeableness, neuroticism, openness and extraversion) were required to a very large extent in millennial leadership. The five elements were significantly related to gender, and only some elements having significant relation to age, educational attainment, and length of service of millennial leaders. Management together with human resource department should constantly review the soft skills of millennial leaders by evaluating their teams’ performance.
