A teacher once told each of her students to bring a clear plastic bag and a sack of potatoes to school. For every person they refuse to forgive in their life’s experience, they chose a potato, wrote on it the name and date, and put it in the plastic bag. Some of their bags were quite heavy.
They were then told to carry this bag with them everywhere for one week, putting it beside their bed at night, on the car seat when driving, next to their desk at work.
