Peace comes from within. Do not seek it without. It can be argued that peace and happiness comes from the subjective internalised perspective of realizing things could be worse and being grateful they aren't. The alternative view that peace and happiness comes from the objective external perspective of having more and better things than at present, while important for growth, can be a never-ending source of jealousy, dissatisfaction and disappointment. A balance of the two, where people are grateful for what they have while striving for more seems the best blended perspective.
I was disappointed in Niagara - most people must be disappointed in Niagara. Every American bride is taken there, and the sight of the stupendous waterfall must be one of the earliest, if not the keenest, disappointments in American married life.
There is only one inborn erroneous notion ... that we exist in order to be happy ... So long as we persist in this inborn error ... the world seems to us full of contradictions. For at every step, in great things and small, we are bound to experience that the world and life are certainly not arranged for the purpose of maintaining a happy existence ... hence the countenances of almost all elderly persons wear the expression of ... disappointment.
There are still many more days of failure ahead, whole seasons of failure, things will go terribly wrong, you will have huge disappointments , but you have to prepare for that, you have to expect it and be resolute and follow your own path.
If the behaviour of babies and small children is any guide, we emerge into the world with our tendencies to imbalance already well entrenched. In our playpens and high chairs, we are rarely far from displaying either hysterical happiness or savage disappointment, love or rage, mania or exhaustion--and, despite the growth of a more temperate exterior in adulthood, we seldom succeed in laying claim to lasting equilibrium, traversing our lives like stubbornly listing ships on choppy seas.
