One should not pursue goals that are easily achieved. One must develop an instinct for what one can just barely achieve through one’s greatest efforts.

To be womanly is one thing, and one only; it is to be sensitive to man, to be highly endowed with the sex instinct; to be manly is to be sensitive to woman.
Physical bravery is an animal instinct; moral bravery is much higher and truer courage.
Monstrosity? What you see before you is the first of a new species. I call it Experiment 626. He is fire-proof, bullet-proof, and can think faster than super computer.

Robots do not hold on to life. They can’t. They have nothing to hold on with – no soul, no instinct. Grass has more will to live than they do.
by Karel Capek
Art is not the application of a canon of beauty but what the instinct and the brain can conceive beyond any canon. When we love a woman we don’t start measuring her limbs.
In art as in love, instinct is enough.
That was my first instinct too. Or a DWI… anything but this!
