'Tis too late to be ambitious.

-Browne, SirThomas
  Hydriotaphia (Urn Burial), ch.5.

Seldom can the unhappy be persuaded that the evil of the day is sufficient for it; and the ambitious will not be content with the present splendour, but paints yet more glorious triumphs, on the cloud curtain of the future.

-Carlyle,Thomas
  Signs of the Times.

L'esclave n'a qu'un ma|"tre; l'ambitieux en a autantqu'il ya des gens utiles a'   sa fortune. A slave has but one master; an ambitious person has as many as he needs to make his fortune.

If the banks were conservative just now [1955], it was because bankers still awoke in the middle of the night, trembling and sweaty with thoughts of the Crash. But intimeanewgenerationwouldtake over: ambitious, overcompetitive young men to whom1929 would be merelya date on a page; such menwould sever theroots of memory as if with an ax, not realizing that those tendrils were also the rudder cables.
