One of my favourites is the answer Robert Adams gives to the question why people photograph: "to keep in tact an affection for life". For me it's as much about the search for meaning, insights, beauty etc. that goes along with being a curious human being. Others paint, write, sing, play, meditate etc. Special would be when someone else generates their own affection about life when they look at one of my pictures. It's not just up to me to say!
