My approach is simple: I do small repetitions every day. Flashcards, apps, notes on my phone, and notes in a notebook help reinforce the material. But the most important thing is using the language in everyday life: I try to think, speak, and even write down my thoughts in the new language. This makes learning engaging, and my brain gets a full-fledged "workout."
Sometimes I notice a "snowball effect": new words connect with familiar ones, phrases pop up naturally, and my memory becomes sharper. Even when I accidentally forget a word, the process of recalling it trains my brain and makes it stronger.
Learning a language isn't just about developing communication skills; it's a real memory workout. And believe me, the feeling when your brain works like clockwork and words come to you easily is worth all the effort.
