No one can take from us the joy of the first becoming aware of something, the so-called discovery. But if we also demand the honor, it can be utterly spoiled for us, for we are usually not the first. What does discovery mean, and who can say that he has discovered this or that? After all it's pure idiocy to brag about priority; for it's simply unconscious conceit, not to admit frankly that one is a plagiarist.
Johann Wolfgang von GoetheThe really unhappy person is the one who leaves undone what they can do, and starts doing what they don't understand; no wonder they come to grief.
Johann Wolfgang von Goethe
