Write Thank You Notes

Family members (aunts, uncles, grandparents, siblings, cousins, parents)
Tuck the thank you notes to parents under their pillows, or tape on the mirror in their bathroom, or set in the refrigerator, or slide into work spaces, obviously a place they will find them and have a quiet moment to read your special message.
Make sure your note says more than just "Thank you," but includes examples of gratitude. Maybe you're grateful for clean laundry, great meals, all the driving to and from school, music lessons, athletic practices and games, quiet times together, etc. Think of one special moment this past year that meant something particularly special to you. Maybe it was the hike you took with Dad or the cooking lesson with Mom, or learning how to wakeboard. You know what wonderful things you've done with your family. Just let them know you haven't forgotten and that you are grateful. Don't forget grandparents, brothers and sisters, aunts and uncles.
People at church (SS teacher, fellow classmates, minister, priest, youth pastor, choir director, clerk, etc.)
If you start early enough, it is a nice gesture to write a thank you note to your city's mayor, state's governor, your country's president or prime minister, or men and women serving your country in the military.

Look for all kinds of opportunities to express gratitude.
