I wish I knew my purpose in life.

All I really know towards that aspect is that I want my purpose in life to be to help as many people as I can live a better life, and I feel that should be the purpose of life in general. I mean, each and every one of us didn’t just magically get this far; we’ve had God and numerous people helping us along the way. I KNOW that everybody has a purpose in their life, and that purpose is to give back to everybody who have given us so much, but I do not know the details as to how, when, what, or where; all I know is why.
