These are my Duolingo stats for 2022.
Last year I started using flashcards again and it has improved my vocabulary immensely. I wish I had been using flashcards from the beginning. My vocabulary would be a lot bigger now. Probably double or more in size.
I put flashcards up all around the house. I put them above the sink in the kitchen and the bathrooms. I have them clipped in piles on the dining table and next to the couch. I also have them in the bedroom to look at before I go to sleep.
My main target language is Korean, but last year I started learning Finnish. I have no reason to learn Finnish, but I love it so much! It is such a fun language and the grammar is so close to English that you end up learning it faster than other languages.
I speak it to my dog sometimes and he seems to understand. He likes it. 😆 
I found a library book at the digital library that lists only Korean translated to Finnish vocabulary words. So, I made flashcards where I can learn both languages at the same time. I heard that it’s better to learn more than one language at one time, so this works out great for me.
