I like trackers that are simple. As much as I'd like to be, I'm not a daily journal person. It requires too much effort in addition to a day of heavy writing. That's where Notion's checkboxes come in nicely. For beginners, checkboxes are a great place to start with personal databases and formulas as well. If you're looking for a creative way to dive into formulas, take a look at the water insult tracker (link below) and let me know what you've done to keep things interesting inside Notion.
