I have a love affair with my city, Rome, and I don't keep it secret, I actually take pictures over pictures of her, and the more I do it, the more I know her, the more I feel I love her, and that she loves me in return.
Some of those pictures get published somewhere, most don't. Some heir will find them, one day, by the thousand, and they will be a nice portrait of the Rome of my lifetime.
I'm basically raising some kind of a "secret" monument to Rome that nobody, but myself and a happy few, will ever admire
PS On a more serious tone, producing images for stock agencies keeps me focused on results and motivated. Ars gratia artis might not work in the long run. In a long journey one has to have a distant point where to look at, or the journey becomes a wandering without direction.
