My letter & diary (28 Sep 2021)

Hello Mandela~

I'm going to write my english letters and diary on here from now.
I expect to improve my expression skills in English.
If it is possible, i hope to write the diary 4 times a week.
Please reply with my sentences corrected.
Additionally, i would like for you to suggest some good expressions.

Thanks for your support and teachings.
Have a good day.
Bye.
