The Lucas Paradox

The Lucas paradox or the Lucas puzzle is the observation that capital does not flow from developed countries to developing countries.

It is not that we have a short time to live, but that we waste a lot of it. Life is long enough, and a sufficiently generous amount has been given to us for the highest achievements if it were all well invested. But when it is wasted in heedless luxury and spent on no good activity, we are forced at last by death’s final constraint to realize that it has passed away before we knew it was passing. So it is: we are not given a short life but we make it short, and we are not ill-supplied but wasteful of it… Life is long if you know how to use it. – Seneca

Let me never fall into the vulgar mistake of dreaming that I am persecuted whenever I am contradicted. — Ralph Waldo Emerson

What matters most is whether one is extending one’s life or merely delaying one’s death. – Seneca

The first is unpleasant and ill paid; the second is pleasant and highly paid.
—Bertrand Russell

You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete.

  • Brian Cox

When you hear hoofbeats, think horses, not zebras.
Dr. Theodore Woodward

Above all, don’t lie to yourself. The man who lies to himself and listens to his own lie comes to a point that he cannot distinguish the truth within him, or around him, and so loses all respect for himself and for others. And having no respect he ceases to love.
Fyodor Dostoevsky, The Brothers Karamazov


There have always been conflicts.

Life should not be a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside in a cloud of smoke, thoroughly used up, totally worn out, and loudly proclaiming ‘Wow! What a Ride!’
Hunter S. Thompson

Everything should be made as simple as possible, but no simpler.
Albert Einstein

Some books are to be tasted, others to be swallowed, and a few to be chewed and digested.

If you want to make a living flower, you don’t build it physically cell by cell. You grow it from the seed. This hinges on a simple scientific proposition: the great complexity of an organic system, which is essential to its life, cannot be created from above directly; it can only be generated indirectly.
Christopher Alexander

Work hard at your job and you can make a living. Work hard on yourself and you can make a fortune.
Jim Rohn

The world we choose to build is the one we’ll inhabit. Technology empowers both the powerful and the powerless, and if we want a world with more liberty and less control, we’re going to have to fight for it.
Edward Snowden

Anybody can become angry – that is easy, but to be angry with the right person and to the right degree and at the right time and for the right purpose, and in the right way – that is not within everybody’s power and is not easy.

Never be a spectator of unfairness or stupidity…The grave will supply plenty of time for silence.
Christopher Hitchens

Youth is wasted on the young.
George Bernard Shaw

We should do away with the absolutely specious notion that everybody has to earn a living. It is a fact today that one in ten thousand of us can make a technological breakthrough capable of supporting all the rest. The youth of today are absolutely right in recognizing this nonsense of earning a living. We keep inventing jobs because of this false idea that everybody has to be employed at some kind of drudgery because, according to Malthusian Darwinian theory he must justify his right to exist. So we have inspectors of inspectors and people making instruments for inspectors to inspect inspectors. The true business of people should be to go back to school and think about whatever it was they were thinking about before somebody came along and told them they had to earn a living.

Buckminster Fuller

The minute you choose to do what you really want to do, it’s a different kind of life.
Buckminster Fuller

People never leave a sinking ship until they see the lights of another ship approaching.

Wabi sabi

Wabi sabi is a Japanese design concept.

The lucky ones

We are going to die, and that makes us the lucky ones.

All things in moderation, including moderation.
Oscar Wilde (?)

This is the lesson: never give in, never give in, never, never, never, never—in nothing, great or small, large or petty—never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy.
Winston Churchill

Purpose of life

The purpose of life is right in front of us: It’s to create a reality we want to inhabit .

Llama la atención que hasta ahora hemos utilizado principalmente nuestra mayor productividad para consumir más cosas en lugar de disfrutar de más tiempo libre. El desempleo se debe en parte a la falta de ingresos (fundamentalmente un problema de distribución), pero también se trata de una falta de autoestima y estatus social.
Nick Bostrom

Lo único que tiene valor es vivir una vida de forma sincera y correcta. Y sé paciente con aquellos que no lo hacen.
Marco Aurelio

The future is already here — it’s just not very evenly distributed.

Henry Ford

The best way to predict the future is to invent it.
Alan Kay

Nadie se ha convertido en pobre por dar a los demás.
Anne Frank

Man surprised me most about humanity. Because he sacrifices his health in order to make money. Then he sacrifices money to recuperate his health. And then he is so anxious about the future that he does not enjoy the present; the result being that he does not live in the present or the future; he lives as if he is never going to die, and then dies having never really lived.
– Dalai Lama

I use not only all the brains I have, but all I can borrow.
Woodrow Wilson

A man should keep his little brain attic stocked with all the furniture that he is likely to need, and the rest he can put away in the lumber room of his library, where he can get it if he wants it.
Sir Arthur Conan Doyle

The more you use your brain, the more brain you will have to use.
George A. Dorsey

Life is ours to be spent, not to be saved.
D.H. Lawrence


Inspiring words from William Ernest Henley.

I never saw a wild thing sorry for itself. A small bird will drop frozen dead from a bough without ever having felt sorry for itself.
D.H. Lawrence


How to become a man, by Rudyard Kipling.

Sooner or later in life everyone discovers that perfect happiness is unrealizable, but there are few who pause to consider the antithesis: that perfect unhappiness is equally unattainable. The obstacles preventing the realization of both these extreme states are of the same nature: they derive from our human condition which is opposed to everything infinite.
Primo Levi

Any advanced form of technology is indistinguishable from magic.
Arthur C. Clarke / Larry Niven *

God grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom always to tell the difference.
Kurt Vonnegut

El peor enemigo del conocimiento no es la ignorancia, es la ilusión de conocimiento.
Stephen Hawking

People who think they know everything are a great annoyance to those of us who do.
Isaac Asimov

La primera regla de cualquier tecnología utilizada en una empresa es que la automatización aplicada a una operación eficiente aumentará la eficiencia.
La segunda es que la automatización aplicada a una operación ineficiente aumentará la ineficiencia.
Bill Gates

¿Por qué debería temer a la muerte?
Si yo soy, la muerte no es.
Si la muerte es, yo no lo soy.
¿Por qué debería temer aquello que solo existe cuando no lo hago yo?

Cuando dices SI a otros, asegúrate que no te dices NO a ti mismo.
Paulo Coelho

El universo tuvo un día sin un ayer.
Georges Lemaitre

To argue with a man who has renounced the use and authority of reason, and whose philosophy consists in holding humanity in contempt, is like administering medicine to the dead, or endeavoring to convert an atheist by scripture.
Thomas Paine


He has achieved success who has lived well, laughed often and loved much…

The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn.
Alvin Toffler

We are not nouns, we are verbs. I am not a thing…an actor, a writer…I am a person who does things…I write, I act…and I never know what I’m going to do next. I think you can be imprisoned if you think of yourself as a noun.
Stephen Fry

When we are no longer able to change a situation, we are challenged to change ourselves.
Viktor Frankl

It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner,
but from their regard to their own interest.
Adam Smith

To sin by silence, when we should protest, Makes cowards out of men.
Ella Wheeler Wilcox
