I'm sure a few of you have a picture, which no matter how many times you try to take it, you just keep on taking a similar photo every chance you get. I rarely ride in the backseat anymore, and it's even more rare that I sit behind someone with glasses, but on those occasions which I do, I always try to get this photo. And very, very few of them turn out the way I want.
But I keep trying. Because persistence, practice and knowledge are the only ways I will finally get it right.
