Find a small, inexpensive piggy bank for each of your group members, OR go to a local bank and pick up enough deposit slips for each person. If you are using a bank, also have small pieces of paper to write on.
Have each person write on paper or deposit slip where they have invested their lives. (i.e. teaching school, leading a small group, children, music, etc.)
After everyone has done that, take turns sharing what they wrote down.
Encourage them to put the little papers in their banks or the deposit slips in a prominent place so that they can see them every day.
Ask them if they are happy with their investments, and remind them that they choose where to spend their time and energy. Maybe they will want to take time to reevaluate their priorities.
