A sense of purpose is the feeling of having a meaningful reason for your existence. It's about understanding your values, passions, and goals, and using them to guide your actions. It's not a single, static goal, but a dynamic process of aligning your life with what matters most to you. This can involve contributing to something larger than yourself, pursuing personal growth, or leaving a positive impact on the world. Having a sense of purpose provides direction, motivation, and a feeling of fulfillment, enriching your life and giving it a deeper meaning.
