Topics for Notebook entries

Hi guys.
I've been studying English for a while (it would be more meaningful to state a time frame as "a while" could have many interpretations, unless your intention is to be vague). I'm going to ("gonna" is not appropriate for written English unless quoting someone talking) write in this notebook everyday as a new way/method to improve my English. However, I don't have any ideas about which topics to write about. So, let me know if you have any recommended topics. 
Thank you (never use "u " to replace "you" in written English, apart from text messages, etc.

 

One source of ideas for topics might be the IELTS topic lists , there are  quite a few topics available on different subjects. The best topics of course, would be those that interest you.
