Make an effort to say "thank you" to every person who plays a part in your life, no matter how big or small. Expressing gratitude for another person's actions shows that you notice them. Send a quick note telling someone how much you appreciate them, how proud of them you are, or just to say thank you for something they did. You can also help others feel better about themselves by showing your appreciation publicly. Praising another in front of family or coworkers can have an impact that lasts beyond the moment itself.
