perspective

“This is why the same external events or circumstances affect no two people alike; even with perfectly similar surroundings every one lives in a world of his own....The world in which a man lives shapes itself chiefly by the way in which he looks at it, and so it proves different to different men; to one it is barren, dull, and superficial; to another rich, interesting, and full of meaning. On hearing of the interesting events which have happened in the course of a man's experience, many people will wish that similar things had happened in their lives too, completely forgetting that they should be envious rather of the mental aptitude which lent those events the significance they possess when he describes them.” - Arthur Schopenhauer
