If you're doing Heads Up, this is your spot. Every lesson ends with a check-in. Drop it here as a comment starting with your day number, like "Day 4: ..."
You can start any day. You can go at your own pace. Just don't do it alone. Read a couple of other people's comments while you're here and encourage someone.
Your Day 1 screen time number goes here first. No shame. That's where we start.
