The problems of failure are problems of discouragement, of hopelessness, of hunger. You want everything to happen and you want it now, and things go wrong. My first book—a piece of journalism I had done for the money, and which had already bought me an electric typewriter from the advance—should have been a bestseller. It should have paid me a lot of money. If the publisher hadn’t gone into involuntary liquidation between the first print run selling out and the second printing, and before any royalties could be paid, it would have done.

And I shrugged, and I still had my electric typewriter and enough money to pay the rent for a couple of months, and I decided that I would do my best in future not to write books just for the money. If you didn’t get the money, then you didn’t have anything. If I did work I was proud of, and I didn’t get the money, at least I’d have the work.

Every now and again, I forget that rule, and whenever I do, the universe kicks me hard and reminds me. I don’t know that it’s an issue for anybody but me, but it’s true that nothing I did where the only reason for doing it was the money was ever worth it, except as bitter experience. Usually I didn’t wind up getting the money, either. The things I did because I was excited, and wanted to see them exist in reality, have never let me down, and I’ve never regretted the time I spent on any of them.

The problems of failure are hard.

The problems of success can be harder, because nobody warns you about them.

The first problem of any kind of even limited success is the unshakable conviction that you are getting away with something, and that any moment now they will discover you. It’s Imposter Syndrome, something my wife, Amanda, christened the Fraud Police.

In my case, I was convinced that there would be a knock on the door, and a man with a clipboard (I don’t know why he carried a clipboard, in my head, but he did) would be there, to tell me it was all over, and they had caught up with me, and now I would have to go and get a real job, one that didn’t consist of making things up and writing them down, and reading books I wanted to read. And then I would go away quietly and get the kind of job where you don’t get to make things up anymore.

The problems of success. They’re real, and with luck you’ll experience them. The point where you stop saying yes to everything, because now the bottles you threw in the ocean are all coming back, and have to learn to say no.

I watched my peers, and my friends, and the ones who were older than me, and watched how miserable some of them were: I’d listen to them telling me that they couldn’t envisage a world where they did what they had always wanted to do anymore, because now they had to earn a certain amount every month just to keep where they were. They couldn’t go and do the things that mattered, and that they had really wanted to do; and that seemed as a big a tragedy as any problem of failure.
