You go on and on preaching how some people are born with the abilities required to become controllers. And i ask you, if eurocontrol thought that was the case, then wouldn't a failure be a pretty good indicator that you simply don't have what it takes? Why do they allow you to retake the exams?
You are all very narrow minded. You should maybe consider the possibility that a person has the abilities but may simply need some practice to enhance what's already there. If there's nothing there, there's nothing to enhance. That simple.
