My secret is simple: I use the language every day in my everyday activities. I watch movies and TV shows without subtitles, read the news or books in the foreign language, take notes or even keep short diaries in the language. Even simply speaking my purchases in the store or commenting on social media becomes a mini-practice.
Another technique is associations and emotions. I associate new words with specific images, situations, or funny stories. This way, they stay in my head for a long time and come up naturally when I need to speak.
The key to learning a language is consistency and interest. If you make the process engaging rather than painful, results come quickly and without stress. My life hack: immersion, associations, and daily practice—and language stops being an enemy and becomes a true friend.
