Here's an at-home exercise that I do to open my heart. It takes less than a minute but provide me with big payoffs.
Here's what I do:
1. I get a piece of paper from the recycling bin. Turn it over. Then I grab a pencil.
2. I list all the students in my class.
3. I pay attention to the students whose names appear last on my list and make sure to get to know those children a little better the next day.
4. Repeat daily.
P.S. If at first you try this exercise and find there are some students in your class whose names you cannot remember, get to know those kids tomorrow.
