First of all: when you start out on a career in the arts you have no idea what you are doing.

This is great. People who know what they are doing know the rules, and know what is possible and impossible. You do not. And you should not. The rules on what is possible and impossible in the arts were made by people who had not tested the bounds of the possible by going beyond them. And you can.

If you don’t know it’s impossible it’s easier to do. And because nobody’s done it before, they haven’t made up rules to stop anyone doing that again, yet.

Secondly, if you have an idea of what you want to make, what you were put here to do, then just go and do that.

And that’s much harder than it sounds and, sometimes in the end, so much easier than you might imagine. Because normally, there are things you have to do before you can get to the place you want to be. I wanted to write comics and novels and stories and films, so I became a journalist, because journalists are allowed to ask questions, and to simply go and find out how the world works, and besides, to do those things I needed to write and to write well, and I was being paid to learn how to write economically, crisply, sometimes under adverse conditions, and on time.

Sometimes the way to do what you hope to do will be clear-cut, and sometimes it will be almost impossible to decide whether or not you are doing the correct thing, because you’ll have to balance your goals and hopes with feeding yourself, paying debts, finding work, settling for what you can get.

Something that worked for me was imagining that where I wanted to be—an author, primarily of fiction, making good books, making good comics and supporting myself through my words—was a mountain. A distant mountain. My goal.

And I knew that as long as I kept walking towards the mountain I would be all right. And when I truly was not sure what to do, I could stop, and think about whether it was taking me towards or away from the mountain. I said no to editorial jobs on magazines, proper jobs that would have paid proper money because I knew that, attractive though they were, for me they would have been walking away from the mountain. And if those job offers had come along earlier I might have taken them, because they still would have been closer to the mountain than I was at the time.

I learned to write by writing. I tended to do anything as long as it felt like an adventure, and to stop when it felt like work, which meant that life did not feel like work.

Thirdly, when you start off, you have to deal with the problems of failure. You need to be thick skinned, to learn that not every project will survive. A freelance life, a life in the arts, is sometimes like putting messages in bottles, on a desert island, and hoping that someone will find one of your bottles and open it and read it, and put something in a bottle that will wash its way back to you: appreciation, or a commission, or money, or love. And you have to accept that you may put out a hundred things for every bottle that winds up coming back.
