Something special that I have is my diary.
I always carry the diary. I'll give reasons why the diary is special.
First, I have written the diary since I was twenty years old. The diary includes my experiences and feelings. It has much good memories than bad memories, because I don't write bad memories. So, it makes me happy.
Second, my diary's color is violet. I like violet. I bought a violet diary twice. I feel so good whenever I see the diary. I'll buy the violet diary next year at the beginning of next year.
Third, I make a memo of important schedules. I don't forget schedules. And, I feel satisfied with the way I'm living my planned life.
Forth, I write down my expenditure records. Every time I see the diary, I can regret my spendig habit. Then I make an effort to spend less.
I think having the diary is good. I recommend you have a diary whose color is your fovorite color.
