Without music no discipline can be perfect, for there is nothing without it. For the very universe is held together by a certain harmony of sounds, and the heavens themselves are made to revolve by the modulation of harmony. Music moves the feelings and changes the emotions... The very beasts also, even serpents, birds, and dolphins, music incites to listen to her melody. And every word we speak, every pulsation in our veins, is related by musical rhythms to the powers of harmony.
If your still alive your mission on earth is not yet complete. People are happiest when they are so completely engrossed in an activity that they lose track of time and go into what is called a flow state. For this to occur, the activity must be reasonably challenging, neither too easy or too hard. It must be something that is of value to others, and it must be something that you love, that you can be passionate about. Your passion for your work will get you out of bed and into the workplace' even when you don't really feel like it, even when you are discouraged about your progress.
