I do the very best I know how-the very best I can; and I mean to keep doing so until the end. If the end brings me out all right, what is said against me won't amount to anything. If the end brings me out wrong, ten angels swearing I was right would make no difference.

Abraham Lincoln (1809 - 1865), Francis Carpenter, Six Months at the White House, 1867

The less their ability, the more their conceit¹.

Ahad HaAm

Great ability develops and reveals itself increasingly with every new assignment.

Baltasar Gracian

Natural ability without education has more often attained² to glory and virtue³ than education without natural ability.

Cicero (106 BC - 43 BC)

Be systematically⁴ heroic in little unnecessary points, do every day or two something for no other reason than its difficulty, so that, when the hour of need draws nigh, it may find you not unnerved or untrained to stand the test.

Daniel Akst, We Have Met the Enemy: Self-Control in an Age of Excess, 2011

The trick of it, she told herself, is to be courageous⁵ and bold and make a difference. Not change the world exactly, just the bit around you. Go out there with your double-first, your passion and your new Smith Corona⁶ electric typewriter and work hard at ... something. Change lives through art maybe. Write beautifully. Cherish your friends, stay true to your principles, live passionately⁸ and fully⁷ well. Experience new things. Love and be loved if at all possible. Eat sensibly. Stuff like that.

David Nicholls, One Day, 2010

It is a great ability to be able to conceal⁹ one's ability.

Francois de La Rochefoucauld (1613 - 1680), Maxims¹⁰, 1665

Martyrdom... is the only way in which a man can become famous without ability.

George Bernard Shaw (1856 - 1950), The Devil's Disciple¹¹ (1901) act 3

I know of no more encouraging fact than the unquestioned ability of a man to elevate his life by conscious endeavor.

Henry David Thoreau (1817 - 1862)

Ability will never catch up with the demand for it.

Malcolm Forbes (1919 - 1990)

Dressing¹² up is inevitably¹³ a substitute for good ideas. It is no coincidence that technically¹⁴ inept¹⁵ business types are known as "suits."

Paul Graham, September 2004

Nerds don't just happen to dress informally. They do it too consistently. Consciously or not, they dress informally as a prophylactic¹⁶ measure against stupidity.

Paul Graham, September 2004

There is something that is much more scarce, something rarer than ability. It is the ability to recognize ability.

Robert Half

Perhaps the most valuable result of all education is the ability to make yourself do the thing you have to do, when it ought to be done, whether you like it or not; it is the first lesson that ought to be learned; and however early a man's training begins, it is probably the last lesson that he learns thoroughly¹⁷.

Thomas H. Huxley (1825 - 1895)

The Army has carried the American ... ideal to its logical conclusion. Not only do they prohibit discrimination on the grounds of race, creed¹⁸ and color, but also on ability.

Tom Lehrer (1928 - )
