Energy
In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton.
Management
Management (or managing) is the administration of an organization, whether it is a business, a not-for-profit organization, or government body. Management includes the activities of setting the strategy of an organization and coordinating the efforts of its employees (or of volunteers) to accomplish its objectives through the application of available resources, such as financial, natural, technological, and human resources. The term "management" may also refer to those people who manage an organization.
System
A system is a regularly interacting or interdependent group of items forming an integrated whole. Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning.

Manager
As far as possible the duty of a leader is to foresee dissatisfaction and to remedy injustice before complaints are made. To accomplish this he must maintain close contact with the men he controls. Let him go into the trenches if he is a general; let him arrive at the factory with his workmen now and then if he is the manager. He must have some imagination; an understanding of other men's lives is necessary to him, so that he may be able to protect those under him from unnecessary suffering. The secret of gaining their affection is to feel affection for them and to be able to do their jobs as well as they do them themselves. Men endure taking orders, and even like it, if the orders are given intelligently.

If you want to do something that's going to change the world, build software that people want to use instead of software that managers want to buy.
