It is very important that a NLP practitioner is able to listen and see very well. When you work with other people in the way they tell you about their problem linguistically in most cases they also tell you what the solution is. At the same time there are many unconscious movement in their physiology that give away a lot more information about what is the case.

I put forward at once — lest I break with my style, which is affirmative and deals with contradiction and criticism only as a means, only involuntarily — the three tasks for which educators are required. One must learn to see, one must learn to think, one must learn to speak and write: the goal in all three is a noble culture. Learning to see — accustoming the eye to calmness, to patience, to letting things come up to it; postponing judgment, learning to go around and grasp each individual case from all sides. That is the first preliminary schooling for spirituality: not to react at once to a stimulus, but to gain control of all the inhibiting, excluding instincts. Learning to see, as I understand it, is almost what, unphilosophically speaking, is called a strong will: the essential feature is precisely not to “will” — to be able to suspend decision. All unspirituality, all vulgar commonness, depend on the inability to resist a stimulus: one must react, one follows every impulse. In many cases, such a compulsion is already pathology, decline, a symptom of exhaustion — almost everything that unphilosophical crudity designates with the word “vice” is merely this physiological inability not to react. A practical application of having learned to see: as a learner, one will have become altogether slow, mistrustful, recalcitrant. One will let strange, new things of every kind come up to oneself, inspecting them with hostile calm and withdrawing one’s hand. To have all doors standing open, to lie servilely on one’s stomach before every little fact, always to be prepared for the leap of putting oneself into the place of, or of plunging into, others and other things — in short, the famous modern “objectivity” — is bad taste, is ignoble par excellence.
