What Is Self-Talk? How Your Inner Voice Shapes Your Thoughts, Feelings, and Behaviour

You are talking to yourself all day, whether you realise it or not.

This internal dialogue, known as self-talk, plays a powerful role in shaping your thoughts, emotions, and behaviour. Yet for many people, it goes unnoticed.

If the way you speak to yourself was said out loud, would it be kind?

In my work as a psychotherapist, I often see how this inner voice can become overly critical, especially during moments of stress, challenge, or self-doubt.

As the Roman philosopher Marcus Aurelius once said, “The happiness of your life depends upon the quality of your thoughts.”

What Is Self-Talk?

Self-talk is your internal dialogue. It includes your thoughts, judgements, interpretations, and predictions about yourself and the world around you.

Much of this thinking is automatic.

For example:

Negative self-talk might sound like:
“I always mess things up.”

A more balanced response might be:
“I made a mistake, but I can learn from this.”

The situation is the same, but the impact of the thought is very different.

As William Shakespeare wrote, “There is nothing either good or bad, but thinking makes it so.”

How Your Inner Voice Affects Your Emotions

Your thoughts are not neutral. They directly influence how you feel and how you respond.

This is a core principle of Cognitive Behavioural Therapy: it’s not just what happens to you, it’s how you interpret what happens.

For example:

Event: Giving a presentation
Thought: “I’m going to embarrass myself.”
Emotion: Anxiety
Behaviour: Avoidance

Over time, this pattern can reinforce anxiety and reduce confidence.

Why Awareness Is the First Step

Before you can change your self-talk, you need to notice it.

You might begin by asking yourself:

• What am I saying to myself right now?

• Is this thought helpful or harmful?

• Would I say this to someone I care about?

This simple awareness creates space, space to respond differently, rather than automatically believing every thought.

A Final Thought

Your inner voice is always there but it doesn’t have to control you.

With awareness, you can begin to shift how you relate to your thoughts, and in turn, how you feel and respond to life’s challenges.

If you’re finding that your inner critic is affecting your confidence, anxiety, or self-esteem, therapy can help you develop a more balanced and compassionate way of relating to yourself.
