5 Places to Find an Idea Worth Sharing When You Feel Stuck

Your next talk might already be sitting in the notes app on your phone: a school rule that annoyed you, a question from dinner, or a thought you never finished. Even when you feel stuck, a strong idea is usually closer than it seems. The skill is knowing where to look.

‍

The best places to find an idea worth sharing are your own experiences, your school day, your community, your hobbies and interests, and whatever you read, watch, or scroll through. Notice anything that feels unfair or surprising.

‍

In this guide, we’ll show you five familiar places to look, how to shortlist your strongest options, and three quick tests that reveal which idea is ready.

‍

Let’s find yours.

Key takeaways

• A topic is a broad subject, like climate change, while an idea is a specific claim about it. Strong ideas are specific, personal, and show listeners something familiar in a new way.
• Good ideas come from noticing, not expertise, and your teenage perspective is what audiences rarely hear. Look in five places: your experiences, school day, community, hobbies, and what you read, watch, or scroll through.
• Keep a phone note of anything that feels unfair, surprising, or strange. Score your top three ideas from 1 to 5 on care, story, one-sentence clarity, and freshness. The highest total out of 20 wins.
• Test your winner three ways. State it in under 20 words, ask “so what?” three times, and pitch it to a friend in 30 seconds.
• Avoid ideas too big to be specific, borrowed opinions, trending takes, and guessing what judges want. AI tools help with research and spelling checks, but the idea and words must be yours.
• The Learning to Be Heard Challenge asks what difference 100 years from now would excite you most. Entries need a one-minute video and one or two written sentences by 10 January 2027, and selected entries are awarded full or partial TED Summer School scholarships. 

What makes an idea “worth sharing”?

A topic is a broad subject, while an idea is the specific point you make about it. “Climate change” is a topic. “My town’s bus timetable decides who can get to an after-school job” is an idea, because it makes a clear claim about real lives.

‍

Spotting that difference is the first step in how to choose a speech topic. Strong ideas share three markers:

• Specificity: Concrete details give listeners a scene to picture. “Tracking my sleep on an app made me sleep worse” works far better than “technology and sleep”. It names a real habit and a real result. 
• Personal stake: A moment you lived through or a problem you’ve watched up close makes your voice credible. Audiences trust a speaker who explains why the issue matters to them, not just why it matters in general.
• Fresh perspective: Your audience should see something familiar differently, like why the quietest group member often has the best idea. That new angle is what makes listeners remember your talk long after it ends.

You don’t need to be an expert to have a good idea

Those three markers depend on what you notice, not on the qualifications you hold. Many students assume they need years of research first. In reality, your perspective as a teenager is the part audiences rarely hear.

‍

Adult speakers can only remember how a timed exam, a phone ban, or a part-time job feels at 16. You’re living those experiences now, and that gives your observations a freshness expertise can’t replace.

‍

The Learning to Be Heard Challenge rewards exactly this. Entries are judged on potential and motivation rather than polished delivery, accent, or fluency. That makes “I noticed this” a strong starting point.

Where to look for ideas

Noticing beats inventing, so keep a phone note of anything that feels unfair, surprising, or strange, and judge it later.

‍

Here are five places you can start looking.

1. Your own experiences

Start with three kinds of moments: changing your mind, feeling out of place, and teaching someone a skill. Each one can grow into a wider point.

‍

Teaching your grandmother to video call, for example, could become a talk about how patience flows both ways between generations. The moment proves you care, while the wider point gives listeners a reason to care too.

‍

Personal stories also show reflection, the quality that turns an anecdote into something an audience remembers and relates to. Write down what you felt, not just what happened.

2. Your school day

The rules and routines you follow at school every day are easy to stop noticing. Looking at them through someone else’s eyes brings them back into focus.

‍

A new student, for example, would notice the unwritten rules, like where each group sits at lunch. A teacher would see who answers most questions and who rarely speaks. A parent might ask why practical skills like managing money aren’t taught.

‍

Pick the view that surprises you most. That surprise often means you’ve found a routine worth questioning, and an idea worth sharing.

3. Your community

Beyond school, your neighbourhood holds ideas in its shops, parks, and family traditions. Notice what has opened, what has closed, and who uses each shared space.

‍

An older relative can help you spot change. Ask what teenagers did at weekends when they were your age. If they mention a youth club that no longer exists, you’ve found a real shift.

‍

That shift raises questions about where young people gather now and what they’ve gained or lost. One dinner conversation can uncover an idea rooted in a place you know well.

4. What you read, watch and scroll through

In 2021, US teens averaged more than eight hours of entertainment screen time a day, according to Common Sense Media. That’s a lot of opinions to scroll past. Notice the posts you replied to or couldn’t stop thinking about, because those reactions often point to your idea. 

‍

Each week, save the post, video, or headline that sparked your strongest reaction. Comment sections help too, because they show which views everyone repeats and which ones nobody mentions.

‍

That gap is a good place to start looking for your angle. If every comment under a viral clip about screen time blames phones, you don’t need to repeat that view. Instead, ask what teenagers are actually looking for when they scroll.

5. Your hobbies and interests

If you’ve ever defended your favourite game, band, or team against someone who dismissed it, you have an argument ready. You just need to aim it at a wider audience.

‍

Niche knowledge from gaming, sport, music, cooking, or a fandom can carry a much bigger point. A football team’s passing drills, for instance, show how trust is built through small, repeated choices.

‍

That depth is your advantage. When you know one corner of the world well, you can show listeners something they’ve never noticed before.

How to pick one idea from your shortlist

By now your phone note should hold several possible ideas, and the next step is choosing the one worth developing.

‍

Here’s how to narrow your shortlist down to one idea:

1. Pick your top three: Choose the three ideas from your list that still grab you on a second read. Three gives you a real choice without making the decision overwhelming.
2. Score each idea: Rate every idea from 1 to 5 on four questions. Do I care about this? Do I have a story or example? Can I say it in one sentence? Does it show the topic from a fresh angle? 
3. Add up the totals: The highest score out of 20 wins. An idea scoring 17 makes a clearer case than one scoring 12, even if the lower one sounds more impressive.
4. Break any tie: If two ideas share the top score, choose the one you’d still want to talk about a week from now. That lasting interest will carry you through drafting, rehearsing, and recording.

Test your idea before you commit

Before you build a whole talk around your winning idea, give it a quick check to catch weak spots early.

‍

Here’s how to test it in a few minutes:

• The one-sentence test: A listener should be able to repeat your idea after hearing it once, so state it in under 20 words. “Sports teams should rotate captains so more players learn to lead” passes at 11. If yours needs a paragraph, it’s still too broad.  Our guide on how to turn a big idea into one clear message can help you narrow it.
• The “so what?” test: Your lunch queue takes 20 minutes. So what? Students get ten minutes to eat. So what? Hungry students lose focus. So what? Afternoon learning suffers for everyone. Asking three times like this shows whether your idea has real stakes or stops at a complaint.
• The friend test: Pick a friend, set a 30-second timer, and explain your idea out loud. A follow-up question means it’s working, while a glance at their phone means the angle needs sharpening.

Common traps when choosing an idea

The most common trap is an idea too big to say anything specific about. “World peace” leaves listeners nothing to picture, and no short talk can cover it. Shrink it to one place or moment you know, like how two families on your street settled an argument over a shared fence. 

‍

Borrowed opinions and trending topics fail for a similar reason. If your view comes from a parent or a viral post, add something you’ve seen first-hand. With trending topics, find the angle the headlines ignore, such as who a new rule affects. Guessing what judges want backfires too, because it removes your personal stake. Choose what you care about instead.

‍

AI tools create a quieter trap. They’re useful for research and spelling checks, but the idea and the words need to be yours. Otherwise, your talk sounds polished yet belongs to nobody. Use AI to check facts, then close it before you start writing.

Finding your idea for the Learning to Be Heard Challenge

Once your idea passes the tests and dodges these traps, it’s ready to share. The Learning to Be Heard Challenge, a global public speaking competition, is one place to do that. It asks: “Fast forward to 100 years from now. What difference would excite you the most? Why?”

‍

Any idea about today can point towards that future. If you noticed quiet classmates being overlooked, you might picture classrooms where being heard no longer depends on being loudest.

‍

Entries are judged on idea clarity (40%), originality and impact (40%), and reflection and story connection (20%). 

‍

To enter, submit a one-minute video and one or two written sentences by 23:59 UK time on 10 January 2027. Entry is free, and selected entries are awarded full or partial scholarships to our TED Summer School.

FAQs

What makes a good speech idea?

A good speech idea makes one specific claim you care about. “Tracking my sleep on an app made me sleep worse” works better than “technology and sleep”, because it’s concrete, personal, and gives listeners something new. 

Do I need to be an expert to speak about a topic?

No, you don’t need to be an expert to speak about a topic. Your perspective as a teenager is valuable on its own, and research can strengthen your idea once you’ve chosen it.

Can I use AI to come up with a speech idea?

You can use AI for research and spelling checks, but not to come up with your idea. The Learning to Be Heard Challenge requires entries in your own words, so the thinking must be yours.

What if my idea has been done before?

An idea that’s been done before can still work if your angle is new. Add a personal experience, a local example, or a viewpoint nobody else is sharing, and the idea becomes yours.

How do I know if my idea is original enough?

Your idea is original enough when it offers a perspective only you can give. The topic doesn’t need to be new, because originality comes from your experience, a local example, or an unexpected connection. 

How do I choose between two good ideas?

Score both from 1 to 5 on care, personal story, one-sentence clarity, and freshness, then pick the higher total. If they tie, choose the one you’d still want to discuss next week.

Conclusion: your idea is already out there

Finding something worth saying comes down to three steps: notice what stands out, shortlist your best ideas, and test the one that wins.

‍

Your strongest idea is probably waiting in your notes app, your school day, or a post you nearly answered. It grows from noticing, not expertise.

‍

Once it passes the one-sentence, “so what?”, and friend tests, it’s ready to be heard. That clarity is what makes listeners lean in and remember.
