I absolutely cannot see how one can later make up for having failed to go to a good school at the proper time. For this is what distinguishes the hard school as a good school from all others: that much is demanded; and sternly demanded; that the good, even the exceptional, is demanded as the norm; that praise is rare, that indulgence is nonexistent; that blame is apportioned sharply, objectively, without regard for talent or antecedents. What does one learn in a hard school? Obeying and commanding.

When a bishop at the first shot abandons the worship of Christ and rallies his flock round the altar of Mars, he may be acting patriotically... but that does not justify him in pretending...that Christ is, in effect, Mars.
If a writer stops observing he is finished. But he does not have to observe consciously nor think how it will be useful. Perhaps that would be true at the beginning. But later everything he sees goes into the great reserve of things he knows or has seen.
