The young Piet Mondrian was painting over some older canvases he had done.

Why are you doing that?” A friend asked. “Those are perfectly good paintings.
I’m not trying to make paintings,” Mondrian replied, “I’m trying to find things out.

We all began by making photographs for no other reason than to find things out, to “see what things look like in photographs,” as Gary Winogrand said. And it it is the  great reason. Then we slowly turn to making photographs that we can think up, or that our clients can think up. But  it is worth remembering that  what really got us going was making those photographs that we could only get to by doing, not by thinking. If we don’t keep that exploration going as a part of our work, our creativity atrophies.

Doing something for nothing lies at the heart of creativity, and creativity lies at the heart of our lives.
