If you want to build a ship, don't drum up people together to collect wood and don't assign them tasks and work, but rather teach them to long for the endless immensity of the sea. No excellent soul is exempt from a mixture of madness.
Every achievement is a bird on the wing.
When I am working on a problem, I never think about beauty. I think only how to solve the problem. But when I have finished, if the solution is not beautiful, I know it is wrong. A man sets himself the task of drawing the world. As the years pass, he fills the empty space with images of provinces and kingdoms, mountains, bays, ships, islands, fish, houses, instruments, stars, horses, and people.
