purpose in life

So we think about it, we ponder over the small things in life.

We talked about life.
We talked about death.

When I thought about it, living for me was simply just not dying. Once, we were at my grandparents' house and talking about death. My sister said she wanted to know how death feels like. My brother said he was afraid of death, and I half-jokingly, dryly said, " I can't wait to DIE."
the moment I said it, there was this ring of truth to the statement.
and I just can't stop wondering what exactly is my purpose in life.
