If one only wished to be happy, this could be easily accomplished; but we wish to be happier that other people, and this is always difficult, for we believe others to be happier than they are. you are comparing your lot with an ideal which is of course better and therefore you feel worse
Baron de MontesquieuThey who love to inform themselves, are never idle. Though I have no business of consequence to take care of, I am nevertheless continually employed. I spend my life in examining things: I write down in the evening whatever I have remarked, what I have seen, and what I have heard in the day: every thing engages my attention, and every thing excites my wonder: I am like an infant, whose organs, as yet tender, are strongly affected by the slightest objects.
Baron de Montesquieu
