Core Principles of Public Speaking
Public speaking is the single most asked-for job skill in the world. Leaders, teachers, YouTubers, scientists, and CEOs all do it. Good news: it is NOT a talent you are born with. Public speaking follows 5 principles that anyone can learn and practice. Today you will meet all 5.
Principle 1 — Know Your PURPOSE
Every great speech has ONE big reason. Ask: WHAT do I want the audience to:\n\n- **Know** (learn something new)?\n- **Feel** (be excited, sad, hopeful)?\n- **Do** (take an action)?\n\nIf you can finish the sentence "After my speech, I want my audience to ___," you have your purpose. Without one, your speech will wander.
Principle 2 — Know Your AUDIENCE
The SAME speech cannot work for everyone. Ask yourself before writing:\n\n- How old is my audience?\n- What do they already know?\n- What do they care about?\n- What do they find boring?\n\nA speech to 5-year-olds about cats should use simple words and lots of pictures. A speech to veterinarians about cats should include science terms they know. Same topic, different speech.
Principle 3 — STRUCTURE
Every good speech has three parts:\n\n- **Beginning (Hook)** — grab attention. A question, a shocking fact, a short story.\n- **Middle (Body)** — 2 or 3 main points. NEVER more than 5.\n- **End (Call to Action)** — what do you want the audience to do, feel, or remember?\n\nAncient tip: "Tell them what you are going to say, say it, then tell them what you said."
Which of these is NOT a core principle of public speaking?
Principle 4 — DELIVERY
Delivery is HOW you say it. Five tricks:\n\n1. **Volume** — loud enough to be heard at the back of the room.\n2. **Pace** — not too fast. Pause often.\n3. **Pitch** — vary your tone so you do not sound robotic.\n4. **Eye contact** — look at different people.\n5. **Body language** — stand tall, use hands, smile if it fits.\n\nA boring speech with great delivery beats an interesting speech mumbled at the floor.
Principle 5 — PRACTICE
The SINGLE biggest difference between good and bad speakers is PRACTICE.\n\n- Say your speech OUT LOUD at least 5 times before you give it.\n- Record yourself on your phone and watch it back.\n- Practice in front of a mirror or a stuffed animal.\n- Time yourself — did you go over or under your time?\n- Ask a friend or family member to watch and give feedback.\n\nEven the best public speakers in history (Martin Luther King Jr., Steve Jobs, Malala Yousafzai) PRACTICED obsessively. No exceptions.

The Universal Formula
PURPOSE + AUDIENCE + STRUCTURE + DELIVERY + PRACTICE = Great Speech.\n\nLeave out any one, and you lose the audience. Include all five, and you can move a room — whether it is 3 classmates or 3,000 people.
Give a 2-Minute Speech
1. Pick a topic you love.\n2. Decide your PURPOSE (know / feel / do).\n3. Think about AUDIENCE (your family, your class, your teacher).\n4. Write STRUCTURE: Hook, 3 main points, Call to action.\n5. Practice DELIVERY (volume, pace, eye contact) out loud 5 times.\n6. Give the speech to your family.\n7. Ask for feedback: What was the strongest part? What was weakest?\n8. You just delivered a real speech using pro principles!
Steal From The Greats
1. Watch one short famous speech (5-10 min):\n - Martin Luther King Jr. "I Have a Dream" (a part of it)\n - Greta Thunberg at the UN\n - Steve Jobs' Stanford commencement\n - Malala's UN speech\n2. For each, identify:\n - What was the PURPOSE?\n - What STRUCTURE did they use?\n - What DELIVERY tricks stood out?\n3. Write down ONE thing you will steal for your own next speech.
Why This Matters
You will give hundreds of "speeches" in your life — presenting to classes, pitching at jobs, giving toasts at weddings, speaking at town meetings. The investment you make learning these 5 principles now will pay back thousands of times over the rest of your life. Few skills are more valuable.
