Lesson 1 Very often people fail to express appreciation to others because they assume those people realize that you are grateful. In reality, this is not always the case. If you don’t express your gratitude, they may never know and feel extremely undervalued. Always assume that you need to verbalize the appreciation for the big and little things. Lesson 2 Showing appreciation for others is a tremendous way to use your power of speech in a positive way. Write short notes of appreciation to as many people as you can. Think about the people you take for granted. How can you show them they are important? The other person will always be grateful for your thoughtfulness
