"A photographer seeks intimacy with the world and then endeavors to share it."
From Jerry Lopez's essay Learning to See.* One of those "required readings" I believe every serious photographer should have in their well of inspiration. In his essay Lopez shares why he gave up photography. Interesting insights as to why some of us stay with it.
*You can find his essay in both of his books Vintage Lopez and About This Life: Journeys on the Threshold of Memory.
