Not sure where your question is headed. Mine was a reply to the parent which focused on difficult tasks.

People with ADHD experience find it more difficult to choose doing mundane tasks when a more stimulating option is present. Additionally, they are more likely to employ unhealthy coping strategies like avoidance when faced with a chore that is associated with negative emotions. This can cascade into a cycle of feeling like a failure for lack of motivation causing further demotivation. So the difficulty isn't in the task, but in choosing to sit with the task and the associated emotional.
