Why starting can be harder than doing
ADHD involves difficulties in executive functions that help organise behaviour toward a goal. A task can be objectively simple but still demand several hidden operations: choosing where to begin, holding steps in mind, estimating time, tolerating boredom and switching away from something more rewarding.
Strategies that reduce the activation cost
Shrink the first action
Replace “finish the report” with an action that takes under two minutes: open the document, write the heading, or list three bullets.
Externalise the sequence
Put the next three steps somewhere visible. This reduces the need to hold the whole task in working memory.
Use a short timer
Commit to ten minutes rather than completion. The goal is to cross the starting threshold.
Add another person
Body doubling — working alongside another person — can provide structure and accountability even when they are doing a different task.
When “paralysis” may be something else
Severe fatigue, depression, anxiety, sleep deprivation, medication effects and physical illness can all create similar difficulty initiating tasks. Persistent or worsening changes deserve professional assessment rather than being automatically attributed to ADHD.
