How do you find your purpose in life?

For me finding a purpose in life would be doing something I want and love and enjoying life and being happy. That is a purpose being happy which means doing things that make you happy and feel loved. It has to be something that fulfills you. My purpose I guess is holding my rocky family together since my sibling fight alot and I am the only one they don't fight with so I am the link that binds them all. My uncle told me that I am the glue in my family because they all love me so respect me enough to try to get along for me on special occasions anyhow. So I guess I am my families glue..lol

I think everyones purpose for life is to just live it, be as happy as you can, take one day at a time and let fatetake its course, just being here you will be used by destiny to be part of the footprint that everyone leaves, just let things happen in life, if you just be happy and live life to the fullest the rest will take care of it self.
