The Powerful Triangle: How Thought, Feeling, and Behaviour Shape Who We Are
Our daily life is a constant dance between our thoughts, emotions, and actions. These three elements—thought, feeling, and behaviour—are deeply interconnected, influencing each other in ways we often don’t notice. Understanding their relationship is the first step toward personal growth and self-change.

Psychologists often describe this relationship as a cycle:
- Thoughts influence how we feel.
- Feelings influence how we behave.
- Behaviour influences how we think.
This is the foundation of Cognitive Behavioural Therapy (CBT), one of the most widely used approaches in modern psychology.
“The greatest weapon against stress is our ability to choose one thought over another.” – William James, Father of American Psychology
For example:
- Thought: “I’m going to fail this presentation.”
- Feeling: Anxiety, nervousness.
- Behaviour: Avoid preparing properly or skipping the presentation.
This avoidance then reinforces the original thought, creating a negative loop.
Where to Start If We Want to Change Ourselves
Many people try to change by forcing different behaviour (“I’ll just push myself to do it”), but without addressing thoughts and feelings, the change may be temporary or exhausting.
Psychologists suggest:
Start with changing your thoughts, because your thoughts directly shape how you feel, and feelings fuel your behaviour.
Aaron T. Beck, the pioneer of CBT, said:
“If our thinking is flawed, our emotions and behaviour will follow suit.”
By challenging unhelpful thoughts, we can change emotional reactions, which naturally makes positive behaviour easier.
Example 1: Overcoming Social Anxiety
- Old Thought: “People will judge me if I speak.”
- Old Feeling: Fear, embarrassment.
- Old Behaviour: Staying quiet in meetings.
New Thought: “Some people might listen, and I could share something valuable.”
New Feeling: Cautious optimism.
New Behaviour: Speaking up in small moments, building confidence over time.
Example 2: Building a Healthy Lifestyle
- Old Thought: “I can’t stick to diets; I always fail.”
- Old Feeling: Hopelessness.
- Old Behaviour: Overeating when stressed.
New Thought: “Every healthy meal is a win, even if I’m not perfect.”
New Feeling: Motivation, self-compassion.
New Behaviour: Gradual, sustainable eating changes.
When Feelings Lead the Way
While thoughts are often the best starting point, sometimes changing behaviour can also shift feelings and thoughts. Psychologist Albert Ellis said:
“You can’t always control the thoughts that come to mind, but you can control your actions.”
Example: Going for a short walk (behaviour) when feeling low can lift mood, which makes it easier to think more positively.
Practical Steps to Start Change
- Identify automatic thoughts – Notice the mental stories you tell yourself.
- Challenge and reframe them – Ask, “Is this thought 100% true? Is there another way to see this?”
- Act in line with your new mindset – Small, consistent actions will reinforce new beliefs.
- Reflect on progress – Celebrate wins, no matter how small.
Final Thought:
The key to self-change isn’t willpower alone—it’s understanding the invisible loop between your thoughts, emotions, and behaviours. Start with your thinking, nurture healthier feelings, and your actions will naturally follow.
