There is enough space to write a short description of what you did that day or to record something memorable that happened for five years. Five whole years! I think it is so great because it allows you to keep all of your memories in one place and be able to look back on the adventures you've been on and the special everyday moments that you've experienced the last few years. I used to use the Moleskine weekly notebooks as my schedule/organizer and just write down where I went that day or what I did but I'm really excited to fill up this One Line A Day book because it keeps five years of memories all in the same place, rather than having to replace it and find storage for it every year.
Do you keep some sort of journal or use something to jot down your memories?
