Teaching doesn't relate to photographing, at least not for me.
I was a hired gun, more or less.
At times people in the press were also useful to me.
I don't have anything to say in any picture.
I don't really have any faith in anybody enjoying photographs in a large enough sense to matter. I think it's all about finances, on one side.
There's all kinds of people teaching who don't do anything worth a nickel. Likewise in advertising.
