How to Make Art
Before you walk into a gallery, close your eyes for a minute and imagine that your net worth is about 25 million dollars, and have about 500k in liquid assets, and you make, say, a million dollars a year. Imagine a large apartment with a bunch of walls. They look cold and empty. Your rich friends are coming over for a Christmas party in a few weeks. You have a few hundred grand in cash that is earning virtually zero interest. What a waste; you need to do something with that money...
Open your eyes. Now you can see everything from the point of view of your audience. Now go back to your studio and start making some art.
