It might sound careless and artless, but the true reflection of life is this careless motion of art, where the artist does not care about ethical values of his own results. The wind blowing does not care whether it will tear your shirt, it is neither ugly nor beautiful.

All great masterworks of art are on the edge of being lost and found.  On the edge of knowing and not knowing.  Being sure of your own actions and doubting all at the same time.  Look at the complexity of the strokes of Rembrandt's hands: he just didn't know which way to pull the brush.
