Every man knows his own but not others? defects and miseries; and ?tis the nature of all men still to reflect upon themselves their own misfortunes, not to examine or consider other men?s, not to confer themselves with others; to recount their own miseries but not their good gifts, fortunes, benefits which they have, to ruminate on their adversity, but not once to think on their prosperity, not what they have but what they want.
Burton
