In terms of those who should examine themselves and don’t ,despite having the mental architecture to make it easy so to speak, then I guess it’s just that motivation, or rather the lack thereof, is not unique to ADD. I guess stuff has to be bad enough to really bother you on a daily basis in order to motivate you to seek help.
Even without any official psychological issues, people all have their own little issues, belief systems etc that they are programmed with which comes into play in how they function in their daily lives.
That and it’s always easy to see what other people should do because we don’t have the same emotional attachment as they do to their beliefs and fears. I know I’m really good at that ( telling others what they should do)
