I just wanted you to know that there isn’t anything impossible. Besides the occasional impossible task, or the somewhat impossible ability to touch your elbow with your tongue.
What I’m trying to say, is that when you dream you desire to attain the currently unattained. Through your desire, and the gumption to start something new, you will find a way to grasp what has been perceived as out of reach for you.
Now, let me warn against the folly of wanting to become anything, because I fear that leans too closely to becoming nothing at all. Rather, dream to be something, someone, or somebody. Don’t let the hunt for anything become your downfall.
