If you remember nothing else, remember this: Inspiration from outside one's self is like the heat in an oven. It makes passable Bath buns. But inspiration from within is like a volcano: It changes the face of the world.
I think what gets you through a small writing project, is just one burst of inspiration. A book, especially a longer book, it's a different kind of force that pushes you through it. It's a vision of the whole thing.
In ancient times music was the foundation of all the sciences. Education was begun with music with the persuasion that nothing could be expected of a man who was ignorant of music.
Read for yourselves, read for the sake of your inspiration, for the sweet turmoil in your lovely head. But also read against yourselves, read for questioning and impotence, for despair and erudition... and also read those whose darkness or malice or madness or greatness you can't understand because only in this way will you grow, outlive yourself, and become what you are.
