After learning foreign languages and martial arts for over two decades, I’ve discovered that these seemingly disparate disciplines share a surprising number of key principles. There is obviously a big difference between conversations and kicks, but both pursuits require the following three ingredients:

1. Active practice with humans: Languages and martial arts are both complex, interactive skills that require thousands of hours of real-world practice with others.

2. Learning by doing: You can't learn to speak fluently or fight effectively by reading books alone. Strategies can help, but the real learning comes from doing, not studying.

3. Mastery of the basics: Mastery in both fields comes from a deep, intuitive understanding of the fundamentals, extensive repetition, and constant, consistent practice.

This last parallel is especially important, so let's explore it more.

Whether learning Japanese or jūjutsu, the importance of the fundamentals cannot be overstated! But despite being the foundation of progress, the basics are often neglected as learners are seduced by flashy moves, rare vocabulary, and advanced structures—the "shiny nickels" that distract from mastering the foundations.

Siren Calls & Shiny Nickels

There's certainly nothing wrong with following your curiosity and going down rabbit holes once in a while, but this should never come at the expense of continuing to practice the essentials. Strive to expand your vocabulary and polish your grammar, yes, but make sure to keep practicing and refining the quotidian stuff, too.

In my own experience learning languages and martial arts, this siren call away from the basics grows strongest during the "intermediate plateau." Since you've already gotten decent at the basics, it grows tempting to start chasing shiny nickels and advanced knowledge. This can be fun, but it can also be a dangerous distraction.

As Tyler Tervooren argues at Riskology, this abandonment of the basics can lead to big trouble:

“When something goes wrong in a big way—a once great sports team loses to a no-name underdog or a successful business goes under—it’s almost always for the same reason. At some point during their rise, everyone quit paying attention to the fundamentals. They advanced so far and started spending so much time trying to perfect the fancy stuff they lost sight of the basics. And when the basics crumble, the fancy stuff doesn’t matter any more.”

Repetition, Repetition, Repetition

We master words and grammar through extensive exposure and practice in meaningful contexts. In other words, through tons of repetition. It may not be sexy, but repetition is the primary ingredient of flowing fluency. We only get better at what we repeat. A lot!

I've interviewed dozens of the world's most accomplished polyglots and language experts on my podcast, the Language Mastery Show, and almost all of them have told me the same secret to their success: massive quantities of repetition and a relentless focus on mastering the basics.

“I do not fear the 10,000 kicks you have thrown once;

I fear the one kick you have thrown 10,000 times.”

—Bruce Lee

Focus on High-Frequency Words & Structures

When you start learning a new language, focus first on mastering the 500 most commonly used words. This small number of terms accounts for over 70% of the language you'll hear and read on a daily basis! Take this up to the 1,000 highest-frequency words, and you cover 86%!

Similarly, I also recommend reviewing Tim Ferriss' "Deconstruction Dozen" for your target language. In just twelve sentences, you can learn decode how the language works and and master the essential grammar patterns you need to start decoding and using the language.

💡 I include the top 500 high-frequency words for Japanese and Mandarin Chinese in the Digital Bundles of my books Master Japanese and Master Mandarin, as well as Japanese and Mandarin Chinese versions of the Deconstruction Dozen.

Procrastination & Analysis Paralysis

Here's another big problem with skipping the basics: The pursuit of advanced techniques is often used as an excuse to procrastinate (or "procrasturbate" as I call it). We think we need to find the perfect study tools or training regimen to get started, so we spend months researching instead of just getting started and learning through action.

As Arnold Schwarzenegger shared in his recent guide 77 Lessons at 77:

"Focus on the basics. Focus on what you can control. Nothing else matters. I will have people who have never worked out in their life come up to me and ask, 'Should I do a push-pull split, or a bodybuilding split, or full body workouts?' I say, 'It doesn’t matter. Anything is more than you're doing now. Just do something.' People will ask about supplements to help their diet when all they eat is processed food. It doesn't matter. Get the basics right!"

The Four Pillars of Fluency

So if you want to apply Schwarzenegger’s advice in language learning, where should you focus your time and energy? There are four pillars every language learner must master before moving on to more advanced topics. Mastering these will give you the biggest bang for your buck and create a strong foundation for fluency.

1. Pronunciation: Spend time mastering the basic sounds of the language. Clear, accurate pronunciation will help native speakers better understand you, even if your vocabulary and grammar are still limited.

2. Core Vocabulary: As mentioned earlier, focus on mastering the meaning and usage of the most common words and phrases. These unlock basic conversations, better travel experiences, and authentic media.

3. Basic Grammar: You don’t need to know every grammar rule or conjugation to start communicating. Start with common chunks, simple sentences, the present tense, and conjugations for "I" and "you."

4. Listening & Speaking: Reading and writing are important, but aural skills should come first. Flood your brain with listening exposure, mimic native speakers, and practice speaking with tutors and AI-powered tools.

Mastering the basics might not sound glamorous, but there's no other way to get fluent. Even the most complex sentences and esoteric conversations are built upon these four pillars. So remember the wisdom of Bruce Lee and Arnold Schwarzenegger and focus all of your time and energy on mastering the fundamentals.

The journey to fluency or martial mastery begins with a single step: focusing on the basics. So whether you're learning Hangul or Hapkido, commit to daily practice and a relentless commitment to the four foundations. This is the path to becoming a fluent speaker and a formidable martial artist.
