Philip Glass
"In my student days, I knew a lot of composers, many of them more talented than myself. But I learned one thing most of them did not: good work habits. When I was still a teenager, I forced myself to write music during a set period every morning, and I also forced myself to stop at one in the afternoon. I refused to take down musical ideas at other hours, even when they came to me. You might say I trained the Muse to come calling at my hours, not hers. And it worked. For years now, I have gotten my ideas in the mornings and never in the afternoons." -- Philip Glass (Music by Philip Glass, xix)
