Inspirational Quote:
"A great scientist, when he was once asked how he managed to hit upon so much that was new, replied: "By keeping on thinking about it." And indeed it may safely be said that unexpected inspirations are produced by no other means than by the expectation of them. To no small extent they are a success due to character, permanent inclinations, unflagging ambition and persistent work. How boring such persistence must be! And then again, from another aspect, the solution of an intellectual problem comes about in a way not very different from what happens when a dog carrying a stick in its mouth tries to get through a narrow door: it will go on turning its head left and right until the stick slips through."—from Robert Musil, The Man Without Qualities
