People are neurotypical rarely if ever understand what those with ADHD go through. The best description I've heard is that people with ADHD don't have habits: we have trauma.
The meaning of that is that neurotypicals have the capacity to simply go into a rom and do something. It almost passively happens. ADHD people do not. Even getting up in the morning involves 50 questions being mentally asked and answered. Do I need to take something to the bathroom? Did I run the dishwasher? Did I leave the heating on? Do I need to do laundry today? And I'm 5 seconds into my day.
A brain that seeks novelty quickly gets bored with reptition. The only way you form habits is by the trauma of the consequences of not having that habit.
