I have been told that a young would-be composer wrote to Mozart asking advice as to how to compose a symphony. Mozart responded that a symphony was a complex and demanding form and that it would be better to start with something simpler. The young man protested, 'But Herr Mozart, you wrote symphonies when you were younger than I am now.' And Mozart replied, 'I never asked how.'
