On assuming laziness:
If you’ve never had to consider how you’d get from your car onto a sidewalk with no curb cut, into a store/business/residence with step(s) and no hand railings or accessible, flat level, wheelchair-width entry (ideally 36″)
or figure out how you’d hold open a heavy door and time it so you move just before it boots you in the butt and knocks you off balance..
If you’ve never had to conserve your liquid and solid food intake because you weren’t certain of an accessible restroom break..
then the idea of conservation of energy coupled with safety to give peace of mind *not* duplicity of disability just.. might… escape… your radar.
Outpacing others in thought, talk, walk or whatever does not make one superior but might mean that the metrics of “success” and self-esteem need to be recalculated sans comparison to others-whose faculties differ in varying degrees.
Consider that many of us can’t “try harder” or “just focus on the positive” to appease your comfort level and sense of well-being. Even still if the aforementioned is done disability still dictates the necessity of accommodations.
