I too ponder on these questions a lot and I think I have figured out my purpose in life. I am here to love the ones around me, be the air under their wings to lift them up and to be a person who does not burden anyone in any way. I also feel I shine when am not being a fake person and not doing good things just to gain appreciation but to please my God.
That's beautiful--to recognize your purpose is to LOVE! A fulfilling purpose to you and the world around you. Thank you for sharing!
