Creativity

Generally speaking, the germ of a future composition comes suddenly and unexpectedly. It takes root with extraordinary force and rapidity, shoots up through the earth, puts forth branches and leaves, and finally blossoms. I cannot define the creative process in any way than by this simile I forget everything and behave like a mad man; everything within me starts pulsing and quivering; hardly have I begun the sketch, ere one thought follows another… If that condition of mind and soul, which we call inspiration, lasted long without intermission, no artist could survive it. The strings would break and the instrument be shattered into fragments.
--Tchaikovsky
