How to NOT Care What Other People Think of You

Have you ever felt hurt by the idea that someone might not like you — even if you barely know them?

If so, you’re not alone. 

As a therapist, I hear it frequently: clients seeking reassurance, approval, or simply trying to avoid being judged. 

The fear of what others think — especially when we imagine it’s negative — can take up so much emotional space that we forget the most important opinion of all: our own.

This is where Mel Robbins’s book “The Let Them Theory” comes in. And it might just be the shift in perspective you need.

What Is the “The Let Them Theory”?

In her book, Robbins proposes a radically simple yet liberating idea:

“If someone doesn’t like you? Let them. If someone thinks you’re too much? Let them. If someone judges your choices? Let them.”

The theory? 

Stop trying to control or change other people’s thoughts about you. Just let them think whatever they’re going to think.

Why This Works

This idea may sound bold — or even reckless — but it’s supported by well-established psychological principles:

1. Cognitive Distortions: The Mind’s Trap

When we assume others are thinking negatively about us, we often fall into a distortion called mind reading — believing we know what others are thinking without any real evidence. This fuels anxiety and people-pleasing behaviors.

Cognitive Behavioral Therapy (CBT) helps you challenge these distortions by testing their validity and learning to tolerate uncertainty.

Try this: "Do I know this person is judging me, or am I assuming it? What’s the worst that could happen if they are?"

2. Social Comparison Theory

Developed by Leon Festinger, this theory suggests we constantly compare ourselves to others to evaluate our worth. 

But when we base our self-worth on external opinions, we hand over our self-esteem to people who may not even know us.

Try this reframing: “Other people’s opinions are none of my business. My self-worth doesn’t need a vote.”

3. Self-Concept vs. Reflected Appraisals

Your self-concept is how you see yourself. But many people rely too much on reflected appraisals — how they believe others see them — to build that identity. This makes your sense of self fragile.

The healthiest self-concept is one grounded in intrinsic values and personal goals, not in social approval.

Action-Oriented Takeaways

Letting others think negatively about you isn't about being cold or indifferent. It’s about building your emotional resilience and choosing your own narrative. Here’s how to start:

1. Build Internal Validation

Instead of asking, “Do they like me?”, ask:

• “Do I like how I showed up in that situation?”

• “Am I living in alignment with my values?”

2. Practice Thought Diffusion (From ACT Therapy)

When a negative thought like “They probably think I’m annoying” pops up, instead of challenging it, try defusing from it.

ACT technique: Say to yourself, “I’m noticing I’m having the thought that they think I’m annoying.”

This creates distance between you and the thought.

3. Set “Let Them” Reminders

Create a mantra or phone wallpaper that says:

• “Let them think bad thoughts about me.”

• “Not everyone has to get me.”

• “Their opinion doesn’t change my truth.”

Use these in moments of social anxiety or after overanalyzing interactions.

Closing Thought

Not everyone will like you. Not everyone will understand you. And some people will misunderstand you no matter how carefully you present yourself.

Let them.

Freedom comes when we stop managing how others perceive us and start managing how we perceive ourselves. You’re not here to be liked by everyone — you’re here to live in alignment with your own truth.
