Journaling in English is not rocket science. All you really need to do is to write a few simple sentences every day. Just like so:
I hate Russian winter. It's cold, windy and slippery outside. It gets dark really early. The streets look sad and grey. That's why I mostly stay home in winter.
See? Just write 5 simple sentences. We're not trying to create a masterpiece. It's all about practicing the language 😜
