My most precious possession

So, this is a question that I've never made to myself, because I've always appreciated more people, experiences and feelings than material things but, thinking it well, I realize that I really have a most precious possession.
This thing is a copybook (whose cover contains a photo of Colo Colo football team), in which last year I used to write many things, specially poems, and they were about all my thoughts that corresponded just to my most private feelings and emotions. There were many things I might not say to everyone, but in this copybook I wrote many papers about all of that.
For example, sometimes -and I dare to recognize it-, I felt a bit sad or confused, in many stranges ways, and I expressed this world of mine on that poems. Also, when I was in love with a girl, apart from talking to her, secretly I wrote again too.
I didn't write only because a "need" motivated me to do it, if not that I loved doing it and writing, poems or anything, has always been one of my prefered hobbies.
In fact, the quality of my poems is very good, and it's not just because I think it, but another people of my private confidence has told me that too.
Actually, I go on writing on my copybook sometimes, and not only poems, but not as often as before, though I'm sure that if I have time and the motivation to do it -and this last one isn't so difficult- I won't hesitate to write again in my most precious possesion: my copybook.
