If you have not yet kept a diary, it is not easy to do. Writing should not be a temporary act but a continuing habit. For instance, I keep two diaries for myself: my personal diary that I write events, ideas, and daily office plans. But also I have a creative diary that I use to write different issues and ideas of creativity, blogs, and some teaching ideas. I have this special diary because I am a blogger and a teacher. However, if it is your first time to keep a diary, you can keep only one diary where you can keep everything.
