Taking that grid idea even further, why not just use a plain notebook page with the days listed top to bottom... one line per day, that's it. You can add a tiny face or a color dot next to each date if you want extra info, but the shape of it does zero work for you. The whole point of a tracker is to make recording faster and easier, not to add another layer of thought about where your pen goes. Those spiral ones look pretty in photos but they're basically art projects, not tools, and anyone who sticks with one past day 10 is probably just forcing it for the aesthetic. I switched to a vertical list with a simple 1-10 mood scale next to each date and I've actually kept it up for two months now, which says everything about what works.

That 10 day hang is a CHANCE you take, but @thomas_johnson's right about humidity, my last one looked like a fossil on the outside but was pure gold inside.
