The race driver analogy is an interesting one.

In another life, I used to give people demonstration runs on a racetrack.
I would take them around for 3 laps.
The first lap at about 8/10's, the second at around 9.5/10's and if they weren't screaming by then (and many of them were), I'd show them some drifting for the last lap.
When you go into the first corner at around 160km/h then throw the car sideways, it really seperates the wannabees!
At the end of the 3 laps, most of the people were white and shaking, and many people would tell me that they thought they were good drivers, but they could NEVER drive like that, and live.

Same with wannabee photographers.
They THINK they are good, until they start comparing the skills and experience of a good pro tog.
