Your daily actions shape the trajectory of your life. From your morning routine to how you wind down at night, these behaviours—often repeated unconsciously—form the fabric of your identity. But despite the best intentions, many people struggle to build habits that actually stick.
Studies show that about 45% of what we do each day is habitual—automatic and triggered by our environment. This makes habit formation one of the most powerful tools for personal transformation, if you know how to harness it.
Dr. Gina Cleo, a renowned habit researcher, keynote speaker and author, has spent years unpacking the psychology of habits through her research at Bond University. Her work reveals that lasting change isn’t about willpower—it’s about understanding how habits are formed and sustained in the brain.
Dr. Cleo also shares her expertise on various platforms such as podcasts, where she discusses the science behind meeting your goals effectively.
Understanding Habits: The Building Blocks of Behavior Change
Habits are automatic behavioural patterns that are triggered by cues in your environment. These patterns make up nearly half of your daily actions—from brushing your teeth to scrolling on your phone.
At the core of every habit is a four-step loop:
Cue – The trigger that initiates the behaviour
Craving – The motivation or desire that fuels the behaviour
Response – The actual behaviour performed
Reward – The benefit or payoff that reinforces the behaviour
Your brain uses this loop as a shortcut system—each time you repeat a behaviour that leads to a positive outcome, a neural pathway is formed and strengthened. Over time, these pathways become more automatic and less conscious, thanks to the brain’s basal ganglia (the part responsible for habits and routines).
Let’s look at a few everyday examples:
Example 1: Morning Coffee
Cue: Waking up & needing energy
Response: Making a coffee
Reward: Feeling alert and focused
Example 2: Social Media Check
Cue: Phone buzzes & triggers desire for social connection or distraction
Response: Opening the app
Reward: Entertainment or interaction
Understanding this loop gives you the power to deconstruct and rewire your habits deliberately.
The Three Phases of Habit Formation
Habit formation unfolds in three key phases. Knowing where you are in the cycle helps you set realistic expectations and stay the course.
The Initiation Phase
New behaviour is introduced
Requires high mental effort and conscious decision-making
Typically lasts 3–7 days
The Learning Phase
The brain begins to recognise patterns
Behaviour becomes easier but not yet automatic
Repetition strengthens neural pathways
Can take 2–8 weeks
This is where most people give up—but sticking with it is crucial. As Dr. Cleo explains in her book, The Habit Revolution, consistency is key during this phase.
The Stability Phase
Behaviour becomes automatic
Requires minimal mental effort
Takes, on average, 66 days to reach
Research from Dr. Phillippa Lally at University College London shows that habit formation timelines vary: simple habits may take 18 days, while complex ones can take over 250 days. Factors like your personality, environment, and consistency all influence how fast a habit becomes second nature.
Conditioning and Reinforcement: Powerful Forces in Habit Formation
Your environment plays a bigger role in habit formation than most people realise. Cues like time of day, your surroundings, or even who you’re with can trigger automatic behaviours. For example:
Physical space: A tidy kitchen may prompt healthy eating
Time: 9pm might signal bedtime scrolling
Social context: Friends who exercise can encourage movement
Emotion: Feeling stressed may lead to comfort snacking
By becoming aware of these environmental cues, you can use them to your advantage—intentionally setting up your space and routines to support the habits you want.
The Role of Positive Reinforcement
Habits are reinforced when the reward is clear and satisfying. These rewards can be:
Intrinsic – a sense of pride or calm
Physical – endorphin boost from exercise
Social – praise from others
Tangible – like ticking a box or earning a small treat
Dr. Cleo’s research shows that strategic use of rewards, especially in the early phases of habit building, increases the likelihood of success. As the habit becomes more ingrained, external rewards can gradually be replaced with intrinsic motivation.
Reprogramming Unwanted Habit Loops: Strategies for Lasting Change
Breaking bad habits isn't about brute force—it's about understanding your current habit loops and gently reshaping them.
Step 1: Identify the Triggers
Keep a log for a few days. Note:
When the habit occurs
Where you are
What you’re feeling
What you gain from it
Step 2: Replace, Don’t Erase
Instead of cutting a behaviour cold turkey, find a healthier replacement that still meets your underlying need.
Example:
Habit: Scrolling at night
Craving: Relaxation
Replacement: Guided meditation app or a fiction audiobook
Step 3: Use Habit Stacking
Attach the new habit to something you already do.
Example:
"After I make my morning coffee, I’ll write down three things I’m grateful for."
Step 4: Leverage Reward Systems
Make your new habit satisfying from the start. Add a mini reward after completing the action—something enjoyable but aligned with your goals.
Debunking the 21-Day Myth
You’ve probably heard it takes 21 days to form a habit—but that’s more myth than science. That idea came from cosmetic surgeon Dr. Maxwell Maltz in the 1960s, observing that patients adjusted to changes in about three weeks.
Modern research shows it’s far more individualised. On average, it takes 66 days—but depending on the behaviour, it could take anywhere from 18 to 254 days.
The takeaway? Don’t aim for a magic number. Aim for consistency. It’s the steady, repeated practice that locks in new behaviours—not the calendar.
Several key factors influence your personal habit formation timeline:
Complexity of the behavior - Simple habits like drinking water form faster than complex ones like daily exercise
Individual personality traits - Your natural tendencies and motivation levels impact formation speed
Environmental context - Your surroundings and daily routines affect how quickly habits stick
Consistency of practice - Missing occasional days can extend the formation period
Previous behavioral patterns - Existing habits may help or hinder new habit development
Dr. Gina Cleo's research emphasizes that habit formation is highly individualized. Her studies show that focusing on the process rather than a specific timeframe leads to more successful long-term habit adoption.
Five Practical Strategies for Lasting Positive Habits
Building lasting positive habits requires a strategic approach backed by proven methods. Here are research-backed strategies to help you implement new behaviors successfully:
Start Microscopically Small
Break down your desired habit into the smallest possible action
Example: Reading one page instead of targeting an entire book
These tiny actions build momentum and reduce resistance
Stack New Habits onto Existing Ones
Identify established routines in your daily life
Attach your new habit directly after a current one
Example: "After I brush my teeth, I will meditate for 2 minutes"
Design Your Environment for Success
Remove friction from positive habits
Create barriers for unwanted behaviors
Place visual cues in your environment to trigger desired actions
Track Your Progress
Use a habit tracker app or simple checklist
Focus on consistency rather than perfection
Celebrate small wins to reinforce positive behavior
Implement the Two-Minute Rule
Start habits that take less than two minutes to complete
Scale up gradually as the behavior becomes automatic
Example: "Put on running shoes" instead of "Run 5 miles"
The Role of Healthcare Professionals in Supporting Habit Change Efforts
Health professionals have a powerful role in guiding habit change. Research shows patients are 3x more likely to succeed when supported by a trusted health provider.
Effective strategies include:
Brief interventions – short, focused chats during appointments
Motivational interviewing – helping patients explore their why
Progress check-ins – accountability increases consistency
Collaborative goal-setting – making plans achievable and personalised
Digital tools also allow for ongoing support outside appointments, creating a more connected and holistic approach to behaviour change.
Empower Yourself Through Understanding The Psychology Of Habits
You don’t need a total life overhaul to see meaningful results. Lasting change happens through small, deliberate actions repeated over time.
With a deeper understanding of the psychology behind habits—and practical strategies to apply it—you’re well equipped to rewire your routines.
So why not start today?
Pick one habit. Make it microscopic. Pair it with a current routine. Celebrate the win. Then do it again tomorrow.
