Fearless is not the absence of fear. It's not being completely unafraid. It's having a lot of fears, but jumping anyway.
無畏并非毫無畏懼。它不是完全不害怕，而是心懷諸多恐懼卻依然勇往直前。
The Moving Finger writes; and, having writ, Moves on: nor all thy Piety nor Wit Shall lure it back to cancel half a Line, Nor all thy Tears wash out a Word of it.
