Appreciation can make a day, even change a life. Your willingness to put it into words is all that is necessary.
Appreciate the people in your life: those who challenge you, those who trust you, those who love you.
Every morning when I wake up, I kiss her forehead as symbol of gratitude and appreciation and she repays me back with a lovely smile.
Learn to appreciate your positives. It is far too easy for us to get carried away with perceived faults in our character.
