- Catch one harsh sentence you say to yourself.
- Write it down exactly, then write what you'd say to a friend in the same spot.
- Self-compassion makes people more motivated to improve, not less.
- In Mentis: "What The Critic Said, What A Friend Would Say", from chapter 8 of the Overthinking plan.
How do you do it?
- Catch one sentence. Today, notice one harsh thing you say to yourself. It's often in "you" or "always" language: "You always say the wrong thing."
- Write it down, word for word.
- Picture a friend saying they feel this about themselves. What would you actually tell them?
- Write the friend's sentence. Honest, specific and warm. "You said one awkward thing in a long meeting. Everyone does. What would you do differently next time?"
- Read it back to yourself, ideally with a hand on your chest. That's the Mentis audio "Hand On The Chest".
Why does it work?
Most of us are much harder on ourselves than on anyone we care about. We assume the harshness keeps us in line. Research says otherwise. In a set of experiments at UC Berkeley, people who were encouraged to treat a failure with self-compassion studied longer for a retest and were more motivated to make amends for a mistake than those who weren't (Breines & Chen, 2012).
A meta-analysis of 27 randomised trials found that self-compassion programmes reduced self-criticism, rumination, anxiety and low mood (Ferrari et al., 2019). The "friend's sentence" is the simplest everyday version of that work.

What does it look like on paper?
| What the critic said | What a friend would say |
|---|---|
| You're so stupid, you forgot the attachment again. | You sent a quick follow-up and it was fine. Maybe add a checklist step before hitting send. |
| Everyone at the party thought you were boring. | You were tired and quiet. Two people talked to you for ages. That's not boring. |
| You'll never be as good as your cousin. | You're on a different path. Look at how far you've come in two years. |
The friend's column is still honest. It just isn't cruel, and it usually ends with something you can do.
When should you use it?
- After a mistake at work or an argument at home.
- When you're replaying something you said. Pair it with the Overthinking plan's chapter on the replay.
- When you notice "should" sentences piling up.
Where is it in the Mentis app?
Chapter 8 of the Overthinking plan, "The inner critic", is built on this. Its keystone is "The Friend's Sentence". Other activities in the chapter are "The Voice That Would Never Be A Friend's", "Catch One Sentence Tonight", the audio "The Friend Who Answered Back" and "The Motivation Test". If perfectionism is behind your critic, try the good-enough rule.
Frequently asked questions
Won't being kind to myself make me lazy?
Research suggests the opposite. In experiments, people who responded to a failure with self-compassion were more motivated to improve and studied longer for a retest than people who just boosted their self-esteem.
What if the critic is right?
A friend can be honest without being cruel. 'That deadline slipped, let's look at why' is honest. 'You're useless' isn't true, and it doesn't help. Write the honest, kind version.
It feels fake to say kind things to myself.
That's common, and the plan has a lesson for it: 'Why Kindness Feels Unsafe'. It gets easier with practice. Start by writing the sentence, even if you don't believe it yet.
