Humans have their limits, we cannot fly, because we don't have wings yes. But also by understanding one's limits we can start seeking out paths and solutions.

Only this way we managed to start crossing the barriers of land, sea, sky and space. And even though we still have many more things that we can learn and progress about (both externally and internally), we can start striving for these improvements only by believing that these things can be accomplished in the first place.

Maybe not all things are possible, maybe our efforts will prove fruitless regarding our goals. But heck. Maybe we'll find some interesting things along the way so it's worth a try...

... Ok, maybe I overextended a little over there. I'm just some guy on the internet after all.
