So what is a “disciplined” person? For one thing, a disciplined person would have a high “Conscientiousness” scores on the Ronin Personality Indicator (http://www.ronin.dk). You know people like this. They’re rarely late for work, they keep lists, they remember birthdays, and they’re very reliable. Most watch what they eat, and exercise regularly. The Ronin Indicator gives them high marks in efficiency, purposefulness, perfectionism, cautiousness, rationality, and orderliness.
