Emotional intelligence (EI), defined as the ability to recognize, understand, and manage one's emotions and those of others, is an essential competency for entrepreneurs, influencing both their personal well-being and the health of the workplace they create. Entrepreneurship is often marked by volatility, stress, and emotional highs and lows, making EI a vital tool for navigating these challenges. This chapter explores how EI can contribute to mental peace, create healthy work environments, and foster emotional well-being among entrepreneurs. It also emphasizes the importance of EI in moving and handling procedures, a critical aspect in healthcare industries that entrepreneurs can learn from to promote physical and emotional health in their teams. Finally, the chapter ties these findings to the United Nations' Sustainable Development Goals (SDGs), particularly Goal 3 (Good Health and Well-being) and Goal 8 (Decent Work and Economic Growth), highlighting how EI interventions can support broader global well-being objectives.
