Writing a few lines a day is a lovely way to keep a record you can look back on in the future. I try to include notes on the small things I would otherwise forget. You could focus on your mood, events in the news or the milestones of family. The space for each day, whether in the A5 or letter sized planners, allows you to summarise what you have been up to.
