One of the basic NLP presuppositions states: “Feedback vs. Failure – All results and behaviors are achievements, whether they are desired results for a given task/context or not.” Or in short as it is expressed most of the time: “There is no failure, only feedback”. In NLP making mistakes and failing are good. Richard Bandler often says that he achieved so much more than most people because he was more willing to make mistakes than others.

Feedback is an integrated part of the TOTE model. If you generate a lot of feedback, meaning you make a lot of mistakes, this only indicates that the TOTE model is working. Especially if you make sure that you make a new mistake each time you fail.

Two Happy Ones. — Certainly this man, notwithstanding his youth, understands the improvisation of life, and astonishes even the acutest observers. For it seems that he never makes a mistake, although he constantly plays the most hazardous games. One is reminded of the improvising masters of the musical art, to whom even the listeners would fain ascribe a divine infallibility of the hand, notwithstanding that they now and then make a mistake, as every mortal is liable to do. But they are skilled and inventive, and always ready in a moment to arrange into the structure of the score the most accidental tone (where the jerk of a finger or a humor brings it about), and to animate the accident with a fine meaning and soul. — Here is quite a different man; everything that he intends and plans fails with him in the long run. That on which he has now and again set his heart has already brought him several times to the abyss, and to the very verge of ruin; and if he has as yet got out of the scrape, it certainly has not been merely with a “black eye”. Do you think he is unhappy over it? He resolved long ago not to regard his own wishes and plans as of so much importance. “If this does not succeed with me”, he says to himself, “perhaps that will succeed; and on the whole I do not know but that I am under more obligation to thank my failures than any of my successes. Am I made to be headstrong, and to wear the bull’s horns? That which constitutes the worth and the sum of life for me, lies somewhere else; I know more of life, because I have been so often on the point of losing it; and just on that account I have more of life than any of you!”
