Some language learning exercises and tips

These are some of the activities I do. Maybe you'll find them helpful:

Write a mock dating profile for yourself. Describe yourself, list your hobbies and interests, hopes for the future, likes and dislikes, and the qualities you're looking for in a partner. Enjoyed it? Write one for your favourite character/OC.
Try to find a Youtuber who plays your favourite game and does commentary in your target language. I watch this guy a lot.
Describe locations in your favourite books, games, movies, TV shows etc. I like to wander the Hitman maps and write about the different areas, NPCs, and situations I observe.
Write a mock interview with your character/influential figure of choice.
Choose a fairy tale and write your interpretation of it in your target language.
When you're cooking, say what you're doing out loud as if you were talking to a studio audience.
Imagine your mutuals are coming to your city for a visit. Write up a lil guidebook for them describing places of interest. Write an itinerary to practice using the future tense and "first", "then", "after that", etc statements.
A chalk marker might be useful to you. I write important words and phrases that I'm having trouble remembering on my bathroom mirror. I just wipe them away with a damp cloth later.
Review books, albums, movies etc in your target language. Either write down your review or record yourself talking about it.
