Spent the better part of the past 2 and a half decades trying to figure out who I am exactly, and every time I come to a solid, firm conclusion that "I am this guy" something comes down the road that throws the whole thing all topsy-turvey.
I worry a lot about the permanence of my life, my personal story. Not that it should necessarily matter, but I am victim to the human fixation on "immortality" like the rest of us. I choose to communicate my story, my experiences, through photographs of the places I've been, of the people I've met, of the things I've done. It is all I could ever hope for that some hapless Joe happens upon my photographs, has some abstract personal revelation, and his life is permanently altered because the image he's seen was so impactful as to make him a different person for the remainder of his mortal life.
I can't think of a better way to change the world.
