Taking a look around, we can also find examples too many to enumerate.
One can enumerate the principal ones: they can no longer innovate and new rivals steal their customers (Borders, BlackBerry and Nokia); they take on too much debt and banks break them up (EMI); they become distracted by acquisitions and diversifications which underperform (Time Warner and AOL).
But to enumerate these things were endless: I have given the rule, where a man cannot fitly play his own part: if he have not a friend, he may quit the stage.
I haven't read much of foreign poetry and prose, nor do I want to enumerate autumn-related poems and essays in foreign literature.
