The word discipline comes from disciple, meaning to learn. At first, information is grasped about what is humanly possible, followed by true learning via practice. As implementation of the GS process occurs, the results provide initial proof and tangible evidence about the validity of what is within reach. This is the source of motivation, for until we see some sort of proof, there is no incentive to act or invest further. From then on, development becomes more effortless, because with self-knowledge, grows one's personal power.
