You know something?! We're animals! Not only that: we're proud animals! And for good reason, because we're great at that, just like the rest of our fellow creatures. As animals we are prone to evolution, whether we like it or not (although let's get real for a moment: who doesn't like a bit of evolving every other day to sparkle the daily routine?!). Each passing experience and each fleeting thought are helping us make a step farther, but closer to our next version of ourselves. If you want a geeky way of phrasing it, I can tell you that we're being constantly upgraded to exceed the initial parameters of our programming and eventually become entities with unforeseeable thinking patterns. But now I can see that you don't like that. I'm really sorry. Let's go back to the biological perspective and just agree that we're evolving.
We do it incrementally and not always to our own benefit, unfortunately - we're dumb that way. We absorb whatever and become whoever. But sometimes we can close our eyes (not while driving though, let's be clear on that) and have a saying about the currents we are willing to let ourselves drift upon. We can be active participants in building our own path. We don't even have to worry about the design, because we will know instinctually when to go left, or right, or even when a tunnel is necessary - we're smart that way. So if we follow our raw guidelines and have the courage to act upon that which feels right, then we're carbon. (You thought I'll say 'gold' didn't you?! Gotcha).
So let the adventure of your (biological) evolution begin, on your path to that just as exquisite future self.
