Fulfillment lies in fulfilling duty

Fulfilling duty, which is not necessarily a grand mission or vision, leads to feeling useful and valuable to others. Instead of getting stuck in deep metaphysical questions about purpose, one can simply focus on identifying one's duty and consistently doing what is useful to others. By finding what one does that others find valuable, a sense of fulfillment and purpose can be achieved. This practical approach does not require elaborate interventions but can lead to feeling good and useful in day-to-day life.
