—Does such a thing like a "destiny" exist? If so, do we even have a choice?
—We do. Destiny is always in constant evolution. Every single thing we do is connected to the path we are supposed to follow. But it's not a direct link, we can change it, so in the end it won't be the same. In a very cliche way to say, we are the owners of our own destiny.
—So we'll all get to where we must be at some point?
—Everything is connected to something beyond our knowledge, beyond everything that scientists have only dreamed of, something that we don't yet understand, but we submit to it like everything in the Universe does.
—To God?
—To you, me, and everything. To complete our purpose as organic living things, to leave a legacy of ourselves, to nothing and everything at the same time.
—Then maybe my life is pointless for the Universe and life itself.
—No, all creatures are here for a reason. You will find it eventually. For now, just learn, focus on your own business and when it's time, you will know all that you need to know.
