Whats your purpose in this life? Have you figured that out?

People say everyone has a purpose in this life and we have to focus on that purpose and fulfill it. I know people that have known their purpose since they were kids. And that’s so awesome and I wish that was my case. I grew up in a broken home where there was no peace or a role model to go by. Nobody went to school and no one did anything exciting. I was the only one who went to college and have two degrees. But that doesn’t keep you warm at night. I’m 39 years old and have dedicated myself to work. Im married and have been raising a little girl since she was 3 years old. Now she’s 11 years old. But yet i struggle with my purpose in this life. What is it? How do i find it? There is a part of my that feels empty. Don’t get me wrong, i love my family. But yet, i feel and i wonder: What on earth am I here for? Have you experienced this?
