What is the “two-minute rule,” and how can it help? 

For many people with ADHD, starting a task can feel like the hardest step. The two-minute rule is a behavioural activation technique designed to break through that mental barrier. The idea is simple: if something takes two minutes or less, start it now. According to NICE guidance (NG87, 2025 update), breaking activities into small, achievable steps supports task initiation and builds momentum through manageable micro-goals. 

Why the two-minute rule works 

ADHD affects the brain’s executive functions, the mental systems responsible for planning, starting, and sustaining attention. The two-minute rule uses a principle called micro-tasking, where large goals are divided into brief, specific actions. This reduces decision fatigue and delivers a quick dopamine “success hit,” motivating further action. 

NHS guidance, including Sheffield Children’s NHS (2023) and Kent Community Health NHS Trust (2025), recommends step-by-step sequencing and short, time-limited tasks to overcome task paralysis. These small starts make large tasks less intimidating and easier to complete. 

The Royal College of Psychiatrists (RCPsych, CR235, 2023) also supports this CBT-aligned approach, describing it as behavioural activation. By setting very small, time-bound goals, even just two minutes, people can retrain the brain to move from avoidance to action. 

What the evidence shows 

Recent studies in Frontiers in Psychology (2024) confirm that micro-tasking and “just-start” rules improve focus, consistency, and follow-through in ADHD. These short tasks stimulate the brain’s dopamine reward system, reinforcing motivation and building lasting productivity habits. 

Charities like ADDISS echo this advice, teaching the two-minute rule as a realistic, low-stress way to build confidence and reduce procrastination. 

How to use the two-minute rule 

• Start small: Ask, “What can I do in two minutes?” 

• Act immediately: Begin with a micro-task like opening an email, tidying one area, or writing one line. 

• Build momentum: Once started, keep going if energy allows; if not, you’ve still made progress. 

• Reward yourself: Each small win releases a dopamine boost that reinforces consistency. 

Behavioural-coaching programmes such as Theara Change also integrate two-minute and micro-task strategies within NICE-aligned ADHD support frameworks. For those seeking further training or certification in ADHD coaching, resources like the ADHD Certify website offer accredited courses and professional development opportunities. 

Takeaway 

The two-minute rule turns intention into action. Backed by NHS, NICE, and RCPsych evidence, this simple technique helps people with ADHD overcome avoidance, start faster, and sustain motivation, proving that big changes often begin with very small steps.
