"...when Walt Disney was creating, he had three distinct parts to the creative process. The first is the Dreamer, who is a person for whom all things are possible. The Dreamer is allowed to think up anything. He can generate the most extreme flights of fancy and really go for it. He doesn't need to be tied down to realistic expectations, but can allow himself to range freely. Later in the creative process is the Realist. The Realist is the person who sorts things out, who takes the information and the ideas thrown out by the Dreamer, and who starts to give the story shape. Finally, there is the Critic. The Critic is the person who finds the things that don't fit together in the story, and who makes the whole project sit together." [source]
