So, you're learning a language. It's hard to know where to start, because learning a language takes a combination of everything on this list. You can never know too much!
Find a Friend
Bring Your Language Everywhere
Begin With Vocab, and Then Actually Follow Grammar
Talk About Everything, Everywhere
Apply Your Language
Get a penpal
Keep trying
If you've learned a language before, you know that it's possible to hit a rut, where it's awful and terrible and there's no reason to keep going. Don't listen to that, and just keep moving. Find support, find something that's keeps you going. Bonne chance!
