Do we discover our purpose in life on our own or is it shaped by the people around us?

After watching the movie Soul, I had this question in my mind. How do we find our purpose in life? I realized that maybe achieving our personal passion alone is not enough to give life a purpose. We thought that achieving our goals would bring us fulfillment. I somehow thought that purpose is not something we find ourselves, but something that we eventually find through our connection with other people, our family, friends, or even strangers, all contribute to our understanding of purpose. Maybe purpose is not about something that we’ve achieved but about the experiences and relationships we built through our lives. With this, I also want to know your thoughts about it.
