Many people ask themselves "What's my purpose in life?"
For me, I don't think we have a purpose. We're just a living existence. Like animals, like trees, like insects, like plants, we just exist.
Yes, we have a greater intelligence, and we've adapted to life in a different way than other species have, which I think is why people think we're supposed to have some sort of path or 'purpose', but the fact is we just don't. As humans we think too much, we over think things until the point of believing in something that doesn't exist.
We have no path or destiny to fulfill, we're just living breathing things. Like everything else, we're born, we live, we die. We exist, we've existed.
