"As we all know, inspiration, like love, can’t be induced. If we are fortunate, it will happen, falling upon us like a gift from the gods. If we are very fortunate, it will happen more than once. The only thing I could hope for was that I would be at work when the miracle came about; so I worked all the time. And then some seven or eight years ago I came upon this sentence by Ralph Waldo Emerson: 'Do the thing and you will have the power.' I didn't know, and still don't, its exact meaning, but the words had for me a power in themselves, an incantatory power. It was as if, simply by saying the words and in that instant taking hold of the work, I had also taken hold of the power. Now here was a power I could induce. And what's more, the experience was similar to that which I had called inspiration. I believe I had tapped into some universal power. My experience is far from unique. Creative workers in many occupations and professions have experienced a communion with a divine source. It is maybe what Matisse had in mind when he asked himself if he believed in God and answered, yes, when at work."
