Ambition breaks the ties of blood, and forgets the obligations of gratitude.

Sallust

Ambition is so powerful a passion in the human breast, that however high we reach we are never satisfied.

Henry Wadsworth Longfellow

It is the nature of ambition to make men liars and cheats, to hide the truth in their breasts, and show, like jugglers, another thing in their mouths, to cut all friendships and enmities to the measure of their own interest, and to make a good countenance without the help of good will.

Sallust

Ambition is not a vice of little people.

Michel de Montaigne

Ambition should be made of sterner stuff.

William Shakespeare

I’ve got a great ambition to die of exhaustion rather than boredom.

Thomas Carlyle

If boyhood and youth are but vanity, must it not be our ambition to become men?

Vincent van Gogh

Nothing truly valuable arises from ambition or from a mere sense of duty; it stems rather from love and devotion towards men and towards objective things.

Albert Einstein

Ambition is the germ from which all growth of nobleness proceeds.

Oscar Wilde
