The ability for an individual to change the world used to be a dream feasible only by the imagination of a child. Facing the myriad of problems plaguing our species, the matured mind would awaken from its reverie to see reality; it would outgrow the naiveté of hope that it could be the one to cause change. But today, it's different; a microscopic machine implanted into the adrenal medulla has eradicate the colossal plight of self-doubt that once suppressed belief in the attainability of dreams. This invention giving us control over the release of epinephrin, our bodies no longer fear obstacles inhibiting the realization of dreams, so we never yield our naiveté. Without anything holding us back, we're free to share our outlandish ideas with others, and because no one doubts themselves, neither do they doubt anyone else. There's always been a belief that change can happen, but most have doubted they could produce it. This machine has altered this attitude, and great change has happened, for we now truly believe nothing's impossible. So if you doubt you can change the world, fear not, for doubt'll soon subside. But if you don't want to wait, the best way to reach the future is by believing in yourself and following your dreams now. Steve Jobs said, "the ones who are crazy enough to think that they can change the world, are the ones who do." So if you're crazy enough, go out and do it! Someone will. Why not you?
