Picasso said "Every child is an artist. The problem is how to remain an artist once we grow up."
I believe we all start life with our Vision fully intact and guiding us. We start off young, innocent and we've not yet learned to conform or to please others.
For example: as a child when we painted, we painted how we liked things. Perhaps we had red skies, purple horses, blue grass...it didn't matter how the world actually was, we painted it the way we saw it, the way we imagined it or just the way we liked it.
But then someone frowned at our painting and said "skies are not supposed to be red" and then to make things worse, they gave Sally a big smile and a pat on the head because she had painted her skies blue.
We got the message: conform and be accepted, conform to earn praise, conform and you will be happy!
We were quick learners and so we began to conform, and the more we conformed, the more our Vision receded. The more we sought to please others, the less we sought to please ourselves...until one day our Vision disappeared.
And not only did we lose our Vision, we forgot that we had ever once had one.
When I started photographing at age 14, I had a Vision. But as I started to conform, to please others, to care what other's thought (I call these Vision blockers) my Vision receded.
Eventually my Vision lenses got so dark that my Vision was completely blocked.
