"As an exercise in appreciation, try for one hour to feel grateful for every single thing you find yourself doing. When you read, be grateful you can see and read. When you walk, be grateful for the use of your feet. When you talk, be grateful for the ability to communicate with others. For a full hour do not take even the smallest action for granted. Be aware of every detail of what you can do. Anyone who does this daily for even a short time will have a much greater appreciation for everything he does."
