How to celebrate the International Day of Happiness when it feels a bit like the world is on fire – reflecting on Radical Acceptance

It’s International Day of Happiness. As Happiness Ambassador, this is when I’m supposed to be at the peak of my powers. And yet it’s been a bit of a struggle this year as oppressive world events continue to escalate. In response, I’ve been thinking about radical acceptance. This is the idea of fully acknowledging what is, especially when we are faced with a reality that is disappointing or distressing.

How could this possibly help? Well it doesn’t stop it hurting. The problem is your brain tries to protect you from pain by constantly scanning for a possibility that this isn’t reality.

“I can’t believe this is happening” “If only…”

This resistance drains you. It adds a second layer of suffering to the negative emotions you’re already experiencing, which only serves to amplify your distress. When you get stuck in a loop of wishing things were not as they are, it’s easy to become overwhelmed. To avoid spiralling in outrage or disbelief, you must accept what is real.

If I’m making that sound simple, let me tell you I am RUBBISH at it. Possibly there is no one worse. Which is why I had to look a little closer.

Where has this idea come from?

I first heard the term radical acceptance from a man speaking about the way he continued with life after the death of his son. This is such a nightmarish version of reality that it hooked my attention. It felt… almost brutal, and yet, the man said it had saved him.

Radical acceptance comes from dialectical behavioural therapy, a clinical approach used psychologists. The most recent study on it (2025) showed strong evidence that radical acceptance was a powerful distress recovery tool, even if you’ve never done any other inner work. At risk of sounding glib, you could call it a ‘neuroscience hack’, because it shifts your brain out of a paralysing loop of stress and into something more functional.

Sounds simple, feels awful.

This can feel deeply uncomfortable in the short term. Adult humans are the only creatures who can suffer over things that are no longer happening, or haven’t yet happened. Young children and animals live much more in the present, and therefore can only respond to what is real right now. They feel pain, yes – but only the pain that’s happening in the moment. Crucially, they don’t waste their mental energy scanning for any possibility that it’s not actually happening.

In the modern world, we’re used to control and choice. So naturally, we try to control before we try to accept.

Releasing resistance comes to some people more naturally than others. My parents, for example, are really good at it. They still feel the anger, sadness and disappointment, but they seem to be at ease with ‘letting go’ of what might have been, what they hoped for, and what they cannot control. As a fiery, supercilious teenager, I used to say ‘bless them, they just want a peaceful life.’

Well… yeah?

Acceptance vs Approval.

One criticism of this approach is that radical acceptance encourages passivity in response to the wrongs of the world. In accepting the reality of a difficult situation, we are consenting to the status quo and might make no attempt to improve it.

It’s important to distinguish between acceptance and approval. You can accept what exists and dislike it intensely. You can accept what is, and also seek to change it.

You could argue further that by first accepting a situation, you buy yourself the clarity and energy to either move on from the problem or tackle it. If you need to make a decision, it’s far better to make a decision based on reality. Your brain won’t let you do this easily, if it’s still searching for an alternate reality.

Accept things as they are so you can respond MOST EFFECTIVELY.

It’s also important to remember that not all realities are permanent.

Acceptance vs Consent

Accepting, for example, that a relationship or workplace is toxic is not the same as resigning yourself to staying in it. In many cases, it’s the first step towards leaving. You don’t have to tolerate being treated badly, you just have to notice and accept that it’s happening, and then decide how to respond.

Perhaps the language ‘acceptance’ can provoke misunderstanding here. Accept can mean receive, welcome, acquire, bear or even consent. Antonyms include refuse, reject, and defy.

If you’re stuck on this, it might be helpful to find your own way of putting it. That might be something like:

“choosing to believe what the evidence supports”
“committing to reality”
“allowing the truth to stand”
“choosing to sit with the facts, even when they are uncomfortable”
“facing up to what is”

Accepting reality is not the same as tolerating it. In fact, acceptance is often what enables defiance, challenge and change. By acknowledging reality as it is, you free up the clarity and energy needed to decide what to do next. We see this with campaigners for social injustice. They start with hard truths. Then they press for solutions. Your action might include seeking support, problem solving or even allowing yourself to grieve.

It’s much easier to make good decisions when you’re responding to what’s actually happening—not what you wish were happening.

Acceptance feels invalidating

Ok, but when I’m complaining about something and someone says ‘it is what it is’…. It’s kind of irritating. I want my feelings validated, not shut down.

We can acknowledge both reality, and the impact it has on us.

This is happening
Because of this, I feel….

Radical Acceptance in Practice

Apparently we should practice radical acceptance by starting with small inconveniences. For example, it’s raining on a day you hoped it wouldn’t be.

My eyes: it’s raining. It just is.

My brain: “but I don’t want it to be… I don’t want it to be.”

This is one that exasperates my husband. We’ll be on our way for a family day out. I’m checking the weather apps, and frowning at the sky – why don’t they match? I’ve not packed for rain. I will do this on a loop until we reach our destination.

I can’t control the weather, all I’m doing is wasting energy and putting myself into a bad mood. My kids in the back seat will certainly feel the discomfort of not having wet weather clothes, but for now they are blissfully in the moment.

Once I’ve finally accepted the reality that the forecast lied, I can make a decision – should we stop at a shop and pick up wellies for the kids? Should we switch to an indoor activity? What can we do to salvage the day? Better just to do that at the start of the journey.

You can’t change reality but you can change your relationship with reality.

A Radical Acceptance Action Plan

(Practice on things like unexpected rain, traffic jams, or a cancelled train)

Acknowledge your feelings, let them exist.
This is not fine and I don’t like it, but it is happening.
Notice the urge to resist what is.
Direct yourself back to acceptance
Let go/Take action
