ADHD and Executive Function
Executive function is the real engine behind most day-to-day ADHD difficulty, and understanding it explains a lot that "just be more disciplined" never does.
What Executive Function Actually Covers
Executive functions are the mental processes that let you plan, start, sustain and adjust goal-directed behaviour: prioritising tasks, initiating them, holding information in mind while you work, regulating impulses, and monitoring your own progress. In ADHD, these processes are less consistently available, not absent, which is why capability can look wildly different from one day to the next.
How This Shows Up Day to Day
Difficulty starting tasks even when they matter (initiation), losing track of steps partway through something (working memory), underestimating how long things take, forgetting appointments or commitments despite genuinely intending to keep them, and starting several things without finishing any of them are all common executive-function patterns: not a character flaw and not a motivation problem, even though they're very often read as one, including by the person experiencing them.
Why "Just Try Harder" Misses the Point
Effort and executive function aren't the same resource. Someone can be highly motivated and still struggle to initiate a task, because initiation is a specific cognitive process that ADHD affects directly: willpower doesn't substitute for it. This is one of the more damaging misunderstandings about ADHD, and it's a major source of the shame and self-criticism explored in a separate article.
What Actually Helps
Reducing the executive-function load of a task (breaking it into smaller concrete steps, using external prompts and written reminders rather than relying on memory, and building in structure rather than expecting willpower to supply it) tends to help more than motivation-focused advice. This is exactly the kind of adaptation that runs through ADHD-aware therapy.
