This raises the question: When do you listen to your head and when do you heed your gut? A rule of thumb might be: If it is something to do with practiced activities, such as motor skills (think of the centipede, Van de Velde, or mastering a musical instrument) or questions you’ve answered a thousand times (think of Warren Buffett’s “circle of competence”), it’s better not to reflect to the last detail. It undermines your intuitive ability to solve problems.
