Listen to your heart.
I was secretly rooting for that response, because I consider it to be about the most important thing that I teach them. I'd be a happy camper if in 40 years, that's the one and only thing they remember about their year in first grade. Miss McMorrow taught us how to listen to our hearts. Anyway, I have a few reminders on my walls about this topic. (Here's one that I made.) I also recently revamped another one. Sorry to the person who created this saying. I've had it for so long I can't remember where I found it.
