When you say: "the secret of succeeding with this 'disorder' is to acquire the wisdom to turn it into a quality and use it to your advantage" maybe part of the disorder is to beleive that you have wisdom and you can turn it into a quality???
To be honest, I recognize a bit of myself in that cartoon and I'm sure a few others would as well if they'd only admit it ;) But I would say, the secret of succeeding with this 'disorder' is to acquire the wisdom to turn it into a quality and use it to your advantage. Any profession involving public speaking is a good outlet for such persons and only frustrated potential such as is caricatured here turns it into a true disorder...
