There are some people who naturally bring order. They are motivated to keep things in their right place. They successfully fight the usual chaos of life. They are also efficient users of resources.
In order to do this the disciplined have an attention to detail and precision. They also develop and are comfortable operating within routines. When these routines are learnt and repeated they bring ever increasing efficiency.
When these disciplines are not controlled well, it can be perceived as OCD (Obsessive Compulsive Disorder) or an unhealthy perfectionism. Because of their dislike of disorder, the disciplined don’t work well in chaotic situations. They will want to constantly bring order and when they can’t it will bring stress. Rather, they prefer to have a predictable environment.
This might lead to them being seen as resistant to change. It isn’t that they don’t like change; but rather that they prefer routine.
