Buddha's doctrine: Man suffers because of his craving to possess and keep forever things which are essentially impermanent...this frustration of the desire to possess is the immediate cause of suffering.
It is true to say that the first kill can influence the whole future career of a fighter pilot. Many to whom the first victory over the opponent has been long denied either by unfortunate circumstances or by bad luck can suffer from frustration or develop complexes they may never rid themselves of again.
There's no question that a lot of Americans on both the right and the left are expressing some fears and frustrations about the dislocations brought on by globalisation. Many of those frustrations are legitimate and they need to be addressed.
Depression seems to be related to fear, anger and frustration. When you're in a bad mood, even if you meet with your friends, you don't take pleasure in their company. But when you're in a good mood, even if things go wrong, you can cope with them without difficulty. This is why putting yourself in a good mood, making a point of developing a sense of loving kindness gives you greater inner strength.

The real thing is that you are suffering from your expectations. When they are not fulfilled - and they are never going to be fulfilled - frustration arises, failure arises, and you feel neglected, as if existence does not care for you. Drop expectations for the future. Remain open, remain available to whatsoever happens, but don't plan ahead. Don't make any psychological, fixed ideas about the future - that things should be like this - and much more suffering will disappear.
There is no formula for generating the authentic warmth of love. It cannot be copied. You cannot talk yourself into it or rouse it by straining at the emotions or by dedicating yourself solemnly to the service of mankind. Everyone has love, but it can only come out when he is convinced of the impossibility and the frustration of trying to love himself. This conviction will not come through condemnations, through hating oneself, through calling self love bad names in the universe. It comes only in the awareness that one has no self to love.
The pursuit of perfection is frustrating and a waste of time, because nothing is ever perfect.
The pursuit of excellence is commendable and worthwhile. Therefore strive for excellence not perfection.
Their pitiless ideology only survives because it is maintained by force. But the day comes when the anger and frustration of the people is so great that force cannot contain it. Then the edifice cracks: the mortar crumbles.
