How to write a conclusion that doesn't just repeat everything ✨

[NickWood]

My professor wrote on my last essay: "Your conclusion just repeats your introduction — add something new." I don't understand. I thought conclusions WERE supposed to summarize. What else should I put?

A writing guide I found breaks it down:

What NOT to do:

• Don't start with "in conclusion" (it's cliché)
• Don't just copy your thesis word-for-word
• Don't introduce completely new ideas
• Don't apologize ("this is just my opinion")

What TO do:

1. Restate your thesis in new words. Not "social media is bad" but "the evidence shows platforms like Instagram significantly impact teen mental health."
2. Summarize main points briefly. Not a list, but a sentence bringing everything together: "Between sleep disruption, social comparison, and reduced face-to-face interaction, the case for limiting teen social media is strong."
3. Answer "so what?" Why does your argument matter? "If we want to protect the next generation's mental health, we need to rethink how and when we introduce social media."
4. End with a thought-provoking statement. A question, call to action, or powerful image. "The question isn't whether teens will use social media, but whether we'll teach them to use it wisely."
5. Connect back to your hook. If you started with a story or question, refer to it again. It gives the essay a sense of completion.

I tried this for my current essay. Instead of "In conclusion, social media affects teens," I wrote: "The scroll never ends, but our attention to its effects must. Between disrupted sleep, distorted self-image, and diminished real-world connection, the evidence demands action — not just from teens, but from parents, platforms, and policymakers alike."

It felt weird at first, but my roommate said it actually made her think. Progress!

The "don't introduce new ideas" warning is important. Some people overcorrect and throw in something totally random. Your conclusion should feel like a natural extension of what you've already argued, not a surprise. You're not adding new evidence, you're synthesizing what you've already said and pointing to its implications. That's the sweet spot. Your example does that well — it pulls from your points (sleep, self-image, connection) and asks for action.
