We do not grow absolutely, chronologically. We grow sometimes in one dimension, and not in another, unevenly. We grow partially. We are relative. We are mature in one realm, childish in another. The past, present, and future mingle and pull us backward, forward, or fix us in the present. We are made of layers, cells, constellations.
Do me a favor... Stand up, walk to wherever the nearest window is, and just look outside. You may not know this, but there's an entire planets-worth of summers, friends, sunsets, street lamps, songs, late nights, great films, and night skies waiting for you. Your life is as amazing as you want it to be, but first, you have to let it be that way.
