I don’t remember which writer said this, but in an interview, a prolific novelist was asked, “Do you write only when you’re inspired, or do you write all the time? Do you wait for the muse, or do you just kind of knock it out? You can just sort of spin it out?” And he said, “Well, I do wait for the muse. I write when the muse comes, but fortunately she shows up, like me, every day at 9:00 a.m.

I think it’s very different in what I do. Edison’s work was so much tinkering and trying it out and empirical testing. So much of my work is writing. I don’t know what you call the writing, it’s true that the actual inspiration, say for writing an essay, the outlining of it is probably a 15-minute to half-hour procedure, then you may spend about 20 hours writing it. But the writing isn’t perspiration in the same sense. It’s not inspiration, but it’s something in between. Any profession has a vast amount of tedium attached to it. There’s no sense not admitting it. If you’re passionate about it, tedium can be — not exactly a joy — but can be perfectly tolerable. The tedium of a pianist is 10 hours of practice a day or whatever, not all of which is inspirational. The tedium of an experimental scientist is calibrating the machines and doing it over and over again. The tedium of a paleontologist is poring over a microscope, or using a dental pick to chip away the sand grains from the fossil, or looking at the statistical figures in the columns of a computer printout. Every profession has massive tedium, that’s certainly true. You cannot be a successful professional (without it). But I think if you’re committed to it, as they say, it goes with the territory. It’s part of the work.

A writer is no different than a bricklayer or a bus driver in that sense. You must have discipline. Oscar Wilde said that writing is 10 percent genius, 90 percent discipline. You must have discipline for writing. It is not an easy task. It is very lonely. You’re all alone. You are not in company. You are not enjoying yourself in that sense. You are enjoying yourself in another sense. You are delving into your depths, but you are profoundly lonely. It is one of the loneliest careers in the world. In the theater, you are with companions, with directors, actors. In film. In an office. In writing, you are alone. That takes a lot of strength and a lot of will to do it. You must really be in love with what you’re doing to tolerate the huge loneliness of writing.

Well, the reason I’ve survived for this long is because any film composer that has an extended career learns to work within deadlines. The deadline becomes the motivating factor in the same way that a pro athlete can do these incredible things with two seconds left in the game. It forces them into their best mode. For film composers, the clock does get us into a higher gear.

The first thing to recommend is that they don’t work in some place that they don’t like, that they don’t do things that they don’t like. That they look for what they really want to do and what kind of thing they want to be involved in, or if they want to go it alone by themselves, to find that.

Well yes, but like I said, small mistakes or small failures. We take small failures very often. We have failures in investment. We have failures in operation, but no big mistakes or big failures. How do we take that? Like ordinary business.
