Thing 5: Learnt A Foreign language

Are You Ever Too Busy to Learn a Foreign Language?

The world, as I often like to say, is a dot. But thanks to technology, we’re more interconnected than ever. Whether you’re tuning into a podcast from Seoul or collaborating on a project with someone in Berlin, it almost feels like speaking at least one foreign language, even at a beginner level, is no longer optional. It is now essential if we want to embrace globalisation meaningfully.

I recall that back in medical school, I had grand plans to live a well-rounded life. I knew I wanted to travel someday and maybe even pick up German again (I’d started it in high school). But the dream always felt like something I’d pursue after school. It wasn’t a priority. Social interests, co-curricular activities and endless academic obligations vied for my time. Still, I think younger Wanjiku was onto something.

To be honest, I could have committed just two hours a week to language learning during my final years. It wouldn’t have hurt. It probably would’ve helped.

I have come to appreciate that learning a new language is one of the most enriching things you can do for your brain. It sharpens your memory, improves your focus and boosts creative problem-solving. Switching between languages trains your brain to filter distractions, process information faster and multitask with more ease. You build mental agility and resilience over time, and (catch this) you may even begin to understand your first language more deeply. You start noticing grammar patterns, structure and expression in ways you never did before. Did I mention neuroplasticity? Language learning strengthens neuroplasticity, which is the brain's ability to form new neural connections. This makes it easier to adapt to new information and skills across your lifespan.

Speaking long-term, studies show that bilingual (and multilingual) people experience a delayed onset of dementia and slower age-related cognitive decline. And beyond the science, there’s something beautifully human about it. Language opens you up to other cultures, perspectives and ways of life. You become more empathetic, adaptable and (of course), more globally relevant in the workplace.

So, after a little less than a decade, I finally answered the nudge I’d shelved years ago, and I’m so glad I did!

Dear medic, are you flirting with the idea of learning French, German, Chinese, Dutch, or even your native mother tongue? I believe you can do it. And I think you should!

Sure, it will take some intentional scheduling. Yes, your timetable might need some tweaking. But it’s worth it. And future you will thank you, probably in multiple languages 🤭.
