I have attempted to show that happiness is, for the most part, within the individual’s own grasp. Happiness comes from within the individual and not from without. Unhappiness must not be confused with pain, either mental or physical, for pain is a normal reaction, to a harmful stimulus which all are liable to feel; it is for the most part beyond the individual’s control so long as the stimulus persists; but the peace of mind, the absence of worry, of irritability, of perpetual uneasiness, which we call unhappiness, lies within the control of everybody. It largely consists in continually recognising what facts are unchangeable, and ceasing to bemoan or phantasy about these unchangeable facts. It is true that the road to happiness may be difficult if we have long been accustomed to tread the path of Narcissism, but it is equally true that if the advice laid down in this book be followed patiently and systematically, a very much happier frame of mind will be attained as a result. In a few cases, Narcissism is not a predominant factor causing the temperamental disturbance although superficially it may appear to be so. In such cases (where other primitive instincts are really of paramount importance) the same degree of improvement will not be attained by this method of self treatment and only a more prolonged course of regular psycho-analysis is likely to produce the desired result. Happiness is not to be found by seeking happiness in the direct sense. This, I am aware, sounds very much like a mere high-sounding thought of a writer. It is the sort of phrase that people dismiss with the remark, “That is all very well in theory.” This statement, however, is not made from any moral or sentimental point of view, nor on any purely theoretical grounds, but as a scientific fact, which has been demonstrated as the result of psychological research. It may be interesting to note here how much the psychology of happiness is in agreement with many of the teachings of the New Testament, although a different terminology and mode of expression may be used. It was pointed out earlier how the individual who employed too much phantasy thought in youth might worry himself into an early grave, although he was the same individual who most desired a long life. It has now been shown that happiness does not come to those who seek happiness, but to those who can adapt themselves to realities, that is, to those who can control their Narcissism. Narcissism is not so very different from the word “self,” as used in Christian teachings, and any who are interested enough to compare them will find that there is considerable parallelism between Christian teaching and certain psychological observations.
