Imagine that you are having an out-of-body experience, observing yourself on an operating table while a surgeon performs open heart surgery on you. That surgeon is trying to save your life, but time is limited so he is operating under a deadline—a literal deadline.

Or do you want him sweating and swearing?
Do you want him behaving like a professional, or like a “typical developer”?The Clean Coder by Robert C. Martin
