Make Good Art

Excellent advice. Here are a few of my favorite quotes from Neil Gaiman's commencement address to the University of the Arts (2012):

Work-Life

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. 

Payoffs

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. 

No Regrets

The things I did because I was excited and wanted to see them exist in reality have never let me down and I never regretted the time I spent on any of them. 

The Diminishing Returns of Being a Perfect Freelancer

You get work however you get work, but people keep working in a freelance world—)and more and more of today's world is freelance—)because the work is good, and because they're easy to get along with, and because they deliver the work on time. And you don't even need all three. Two out of three is fine. 

People will tolerate how unpleasant you are if your work is good and you deliver it on time. People will forgive the lateness of your work if it's good and they like you. And you don't have to be as good as everyone else if you're on time and it's always a pleasure to hear from you.
