Setting mental health boundaries as a business owner is crucial for advocating oneself and creating a solid foundation to avoid confrontations with clients. To start, one must know more about themselves and how they work, including their ideal work schedule, working style, financial needs, and emergency protocols. By setting boundaries such as work hours, client selection, work-life balance, financial management, and contingency plans for bad mental health days, individuals can create a healthy foundation to prevent stress and mental health crises. These boundaries are not only important for personal well-being but also for business success, allowing entrepreneurs to stay accountable and focused on their goals while maintaining a better quality of life.
