“I figured if I said it enough, I would convince the world that I really was the greatest.” 🥊
Muhammad Ali, who reigned as an Olympic gold medalist and World Heavyweight Champion, remaining the greatest icon in 20th-century sports history. Before stepping into the ring where tens of thousands of spectators and a fierce opponent awaited, how did he control extreme fear and performance anxiety?
Ali looked into the mirror every morning and shouted loudly even in front of reporters during training: “I am the greatest.” Rather than mere boasting, he adhered to self-affirmations that deeply engraved a winning mindset into his brain and subconscious. The power that overcame pressure from the public and media to make him a true champion was his decisive positive self-declaration shouted in front of the mirror every morning.
In today’s post, we introduce the sports psychological principles behind Muhammad Ali’s ‘self-affirmation’ routine and a modern mindset routine.

1. The Power of Self-Declaration That Activates the Brain’s Reward System
When we feel anxious or lack confidence, the brain secretes excess cortisol—a stress hormone—reducing our ability to cope with crises. According to neuroscience, shouting positive affirmations aloud while looking in the mirror stimulates the brain’s ‘Medial Prefrontal Cortex’ and reward system. This self-affirmation declaration tunes the brain to be less sensitive to threatening information, awakens self-efficacy, and increases stress resilience. The moment you call yourself the greatest, your brain actually begins preparing to activate physical and mental energy aligned with that value.
2. 3-Step Practical Routine for Modern Professionals
Drafting Positive Affirmation Sentences
Write down your own short and powerful positive affirmation sentence written in the present tense (e.g., 'I trust myself and move forward step by step') on a card or smartphone note.
Reading Aloud Firmly 3 Times in Front of the Mirror
Before starting your morning routine, stand in front of the mirror and look directly into your own eyes. Looking at or reciting your prepared affirmation card, read it aloud 3 times in a powerful and decisive voice.
Visualizing a Successful Day for 10 Seconds
After finishing the declaration, close your eyes and vividly visualize in your mind for 10 seconds today's version of yourself acting with confidence as your determination is realized.
3. Declare Firmly in the Present Tense, Not as a Mere Wish
For positive affirmations to stimulate the brain’s subconscious, linguistic structure is key. A wishing tone such as ‘I want to become…’ can highlight a state of deficiency to the brain. Just as Muhammad Ali asserted ‘I am the greatest,’ you must firmly declare to yourself in present-tense sentences that define an accomplished state or clear capacity—such as ‘I have the ability to achieve my goals’—for true cognitive transformation to occur.
📌 Frequently Asked Questions (FAQ)
It feels awkward because it feels like lying to myself that I am the greatest. ▼
It is natural to feel awkward at first due to Cognitive Dissonance. The key is not verifying current factual truth, but opening new possibilities for your brain. As you repeat this, neuroplasticity will reorganize neural circuits, causing the awkwardness to vanish and solidify into belief.
Is it effective only if I shout it loudly out loud? ▼
The best approach is directly perceiving the vibration of your voice through hearing. However, if your environment makes speaking out loud difficult, whispering or intently repeating each word in your mind with strong focus (Silent Self-talk) also provides sufficient positive stimulation for brain activation.
