And after that, the biggest problem of success is that the world conspires to stop you doing the thing that you do, because you are successful. There was a day when I looked up and realized that I had become someone who professionally replied to e-mail, and who wrote as a hobby. I started answering fewer e-mails, and was relieved to find I was writing much more.

Fourthly, I hope you’ll make mistakes. If you’re making mistakes, it means you’re out there doing something. And the mistakes in themselves can be useful. I once misspelled Caroline, in a letter, transposing the A and the O, and I thought, Coraline looks like a real name . . .

And remember that whatever discipline you are in, whether you are a musician or a photographer, a fine artist or a cartoonist, a writer, a dancer, a designer, whatever you do you have one thing that’s unique. You have the ability to make art.

And for me, and for so many of the people I have known, that’s been a lifesaver. The ultimate lifesaver. It gets you through good times and it gets you through the other ones.

Life is sometimes hard. Things go wrong, in life and in love and in business and in friendship and in health and in all the other ways that life can go wrong. And when things get tough, this is what you should do.

Make good art.

I’m serious. Husband runs off with a politician? Make good art. Leg crushed and then eaten by mutated boa constrictor? Make good art. IRS on your trail? Make good art. Cat exploded? Make good art. Somebody on the Internet thinks what you do is stupid or evil or it’s all been done before? Make good art. Probably things will work out somehow, and eventually time will take the sting away, but that doesn’t matter. Do what only you do best. Make good art.

Make it on the good days too.

And fifthly, while you are at it, make your art. Do the stuff that only you can do.

The urge, starting out, is to copy. And that’s not a bad thing. Most of us only find our own voices after we’ve sounded like a lot of other people. But the one thing that you have that nobody else has is you. Your voice, your mind, your story, your vision. So write and draw and build and play and dance and live as only you can.

The moment that you feel that, just possibly, you’re walking down the street naked, exposing too much of your heart and your mind and what exists on the inside, showing too much of yourself, that’s the moment you may be starting to get it right.

The things I’ve done that worked the best were the things I was the least certain about, the stories where I was sure they would either work, or more likely be the kinds of embarrassing failures people would gather together and talk about until the end of time. They always had that in common: looking back at them, people explain why they were inevitable successes. While I was doing them, I had no idea.
