I have just discovered a free online journal which you can join.
sign up at https://penzu.com/ It is a personal journal and you can choose to keep it a secret or email and share with everyone in your class or whatever group you create.
I think this is a cool way to make sure you write everyday. You can even post pictures.
The fastest way to improve your English is to use the language everyday. Keeping a journal is one way. If you don't know what to write, just google journal prompts and there are thousands to choose from.
