Could you correct my sentences? (I want to know how to use the word “would” in future sentence.)

I’ve started handwriting diary in Japanese since last Friday. The diary’s form is unique. It is divided three parts in each page, so I can keep the diary for three years. Moreover, I can read my today’s journal on the same day of the next year. I think it’s interesting. I look forward to writing next year, because I would want to know what I have done or thought of one year ago.

HI.  The writing is good, just some small problems.  It is difficult in English that we must always use these articles.  So, "a" handwriting diary  Also, "divided into three parts..."  You also use: "today's journal entry on the sam day next year."  "I look forward to reading next year because I am interested to know what I thought and did one one year prior."

Since last Friday, I’ve been keeping a handwritten diary in Japanese. The diary’s form is unique. Each page is divided into three parts, so I can keep the diary for three years. Moreover, I can read my today’s journal on the same day of the next year. I think it’s interesting.

Good concept. At the end of the three years, would you begin again, or would it be the end of the project? To keep writing for three years would be a big commitment for some people!
