English Diary: Declaration of Commitment

I have decided to start writing my diary in English today.
Writing is very good for organizing my thoughts.
If so, writing a diary in English instead of Japanese will help me to improve my English language skills at the same time.
I have to do it.
Make it a habit every morning.
