A Simple Tradition
Maybe you’ve seen little notebooks called “One Line A Day”. Each page holds a calendar date and a few lines of space. Every day you add one thought, and each year you fill the line just below the last one.
Start a new daily routine of self-reflection. See every day what this day was like in past years of your journaling.
Maybe you’ve seen little notebooks called “One Line A Day”. Each page holds a calendar date and a few lines of space. Every day you add one thought, and each year you fill the line just below the last one.
You never need to write a whole diary page. One moment, one idea, one little memory is enough. And the magic is that, as years go by, each entry lines up with the ones from your past.
Open today’s date and you’ll see your past selves alongside your new entry. It’s like a personal time capsule that gently shows how you grow and change over the years.
Paper notebooks have finite space. When all lines are filled you need a new one and may never open the old one again. You can lose a book, spill coffee on it, or forget it on vacation.

With One Thought A Day you keep all the good things and none of the bad. It’s always there, on your phone, your computer, or even someone else’s. Your entries are safe.
