Do you write a diary? If you do, try to write it in English. Gradually, you will improve your writing skill.
However, I want you to look for the difference in meaning among diary, journal, logbook. They are great words to learn to build up your vocabulary. Don't forget that you must learn English by using English because learning English through translation cannot give you a thorough comprehension of this target language.
If you kept a diary, what would you write for today? Of course, you can just use the English you have acquired to do the job.
I do not keep a diary. Otherwise, I would have written:
" Today, after rising from bed at 5:30 I opened my back door, which looks to a small empty crop-land newly overgrown with grass. Taking me by a surprise, a powerful cacophony of wail were waffing into my house, ringing deafeningly into my ears. I was taken aback for a while before realizing that it was the cicadas who were heralding the coming of another summer. ......"
See, you can just record in your diary what you first encounter in the day, or what impresses you most.
