Way of making schedules

This is my small notebook when I was a senior in high school, which I used last year. It's an  A5-sized white notebook with a clear cover. A5-size is 148×210mm. My high school gave it to me. It is half the size of A4-size. We can write your schedules for a year. I used to use it until 2020.  

 I’m so  forgetful, so I often forget about any event date, exam date, my homework deadline and so on. I realized the date, and panicked was my usual. Actually, for example, when our teacher said “Only this week, we’ll have a small exam.”, I completely forgot about it most of the time. And then I talked to my friend, “I haven’t studied for the exam!”. It's a miserable episode, but I had a hard time because of my oblivion. Thus, the small notebook helped me to check my schedule. I wrote down my schedule and checked it frequently to remember what I have to do. I wrote down about regular examinations, club tournaments and entrance exam too. Absolutely, I don't forget about those big dates, it's a memorial item for me.

 I think that people who use small notebooks are minorities nowadays. Most of us use smartphones instead of small notebooks. Reminder system is so useful. However, I believe that small notebooks have many good points. When we write down some schedules, we recognize them strongly. It makes our sense of responsibility strong. Reminder system gives us a feeling of security, but it is easy to forget. So I believe that small notebooks are useful even now. And also, writing letters is effective to organize your thoughts. It is useful not only to make schedules but also to manage to sort yourself out. In other words, the small notebook manages your mind. 

 I recommend using small notebooks. When you use it, you can easily remember about your schedule. My idea is that it's a little risky to depend only on the reminder system. To remember your schedule in your head is helpful to do something smoothly. Using small notebooks is effective to do it. How about you use small notebooks with your reminder system?
