I think that we all have a purpose, even though we aren't sure what the purpose is. Some people are needy and that person is here to give you someone to channel attention on. Some people have the right answers or know what to say at the right time.
That is their purpose in life. Some of us don't find out what our purpose is for a long time. Us slow learners have had a lot of potential options placed before us, we are holding out until the right one comes along. The right one will be the purpose that
not only feels right, feels natural, but you just slide into it as if you were just waiting for it to come to you. Some people find their calling early. Some of us hit or miss. I think I am zeroing in on mine. I'll know for sure when it gets here.
