From A List Apart: Imagine you are standing on a bridge casting a net. Above the bridge is your conscious mind, where thoughts come and go like travelers visiting a fair. Below the bridge is your subconscious — the ever-flowing stream of random thoughts, with countless ideas darting through the water like schools of brightly-colored fish. As is often the case where bridges and streams are concerned, a cold and menacing troll lurks nearby. This troll is your “Inner Critic.” The troll, aggressive and mean-spirited, doesn’t give a lick about your Grand Ideas. The troll has but one purpose: to prevent the ideas which playfully zoom about your subconscious from being gathered into the net of your consciousness and made manifest in the world.
