It is important to work in a position that gives free play to the lungs and does not compress the other organs. It is good from time to time to interrupt a spell of close application in order to breathe deeply, to stretch one's limbs in two or three rhythmic movements which relax the body and even prevent it from getting wrinkles. It has been found that slow and deep breaths, taken standing on tip-toe, with the window open, are still more effective as a relaxing agent.
At other times, it is in the morning, on first awaking, that the flashes come.
…Every thinker has experienced instances of early morning lucidity that are sometimes surprising, almost miraculous.
…Quick to your notebook when such a piece of good fortune befalls you.
…
we must get ready in the evening, and we must prepare the night which, after its fashion, and without our intervention links together the periods of our conscious toil
…
to let keen activity give way to a simple familiar routine, in a word, to cease willing up to a point so that the renunciation of night may begin.
Do something, or do nothing at all. Do ardently whatever you decide to do; do it with your might; and let the whole of your activity be a series of vigorous fresh starts.
…
That is the kind of work of which we speak when we say that two hours daily are enough to yield a tangible worthwhile result. Evidently, they are not much; but they really suffice if all the conditions are fulfilled;
Given certain conditions, the more one knows the better; but in fact, as these conditions cannot be realized, and today less than ever, the encyclopedic mind is an enemy of knowledge.
True knowledge, (scientia, science in its fundamental sense) lies in depth rather than in superficial extent. Science is knowledge through causes, and causes go down deep like roots.
It is a painful thing to say to oneself; by choosing one road I am turning my back on a thousand others.
…
Do not be ashamed not to know what you could only know at the cost of scattering your attention.
Nothing is so disastrous as to keep turning one's attention this way and that.
…
Let your mind become a lens, thanks to the converging rays of attention; let your soul be all intent on whatever it is that is established in your mind as a dominant, wholly absorbing idea. Make an orderly series of your different studies, so as to throw yourself into them completely. Let each task take entire hold of you, as if it were the only one.
…
What we are proscribing is the passion for reading, the uncontrolled habit, the poisoning of the mind by excess of mental food, the laziness in disguise which prefers easy familiarity with others' thought to personal effort.
Better go out of doors, read in the book of nature, breathe fresh air, relax. After the requisite activity, arrange for the requisite recreation, instead of automatically yielding to a habit which is intellectual only in its matter, which in itself is as commonplace as gliding down a slope or climbing hills aimlessly.
…
Read only those books in which leading ideas are expressed at first hand.
…
Fundamental reading demands docility, accidental reading demands mental mastery, stimulating reading demands earnestness, recreative reading demands liberty.
So when you want to remember, notice the connections and the reasons of things; analyze them; look for the wy and wherefore, observe the genealogy of happening, the order of succession, and their dependent consequences; imitate the procedure of mathematics in which necessity starts from the axiom and arrives at the most distant conclusions.
On the other hand, when you have to study a precise subject, to produce a definite piece of work, you try to gather material, you read what has been published on the question, you have recourse to all the sources of information at your disposal, you make your own reflections, and you do it all pen in hand.
You must write throughout the whole of your intellectual life.
In the first place one writes for oneself, to see clearly into one's personal position and problems, to give definition to one's thoughts, to keep up and stimulate attention which sometimes flags if not kept on the alert by activity — to make a beginning on lines of investigation which prove to be necessary as onewirtes, to encourage oneself in an effort that would be wearisome in the absence of some visible result, lastly to form one's style and acquire that posession which puts the seal on all the others, the writer's art.
When you write, you must publish, as soon as good judges think you are capable of it and you yourself feel some aptitude for that flight.
This plan of arranging one's tasks according to the demands they make on the brain will have a double advantage: it will prevent overstrain, and will restore its pure value to intensive work.
Then add, and repeat with full certainty: “If you do that, you will bear fruit and you will attain what you desire.“
