One could argue that dreams are futile, that trying takes too much effort, but it's in the stumbling that we learn who we really are. None of us truly know what we're doing or where we stand. It's in the discovery, that's what makes us real and vulnerable and imperfectly human. Even if we don't know why the heck we're still trudging through the dirt, the point is we'll make some destination, we'll write our own journey if nothing else happens.
I see your point, and I agree with a part of what you are saying. People can make their own destiny, and they can find them selves through a journey of their own making. But being shaped by our struggles in life and the lessons we learn doesn’t mean we can’t still follow our dreams. Dreams are just goals that haven’t been reached yet. Plus anything that doesn’t require effort probably isn’t worth it. Anyone can take the easy route.
