ADHD means being cursed with less of the thing everyone agrees makes or breaks an intention: consistent application.

They talk as if this one thing you lack is just a choice equally available to everyone.

You watch as they lose respect for you. Their ethic is so founded on seeing what you lack as a simple moral, a thing chosen by the good.

If it's just a choice, those who make the effort of choosing it are to be admired - and successes will reward them - while those who do not make the effort and do not choose it are to be seen as deserving their failure.

Never mind that someone with ADHD may well be trying harder than others, even much harder, in some important senses. Who finds it easier to ride a bike, the frequent biker or the kid trying to get going for the first time, in fits and starts? Now imagine the fits and starts continue... and continue... and continue... and you can't quit... but everyone thinks you're hopeless or not trying or not worthy or whatever. And *you* think that, sometimes, because what else are you supposed to think? And your thinking it is contagious, so other people think it, and their thinking it is contagious, so you think it, and... you know, it's pretty silly.

Everyone agrees that what you lack is all it takes. And without what you lack, nothing will ever work.
