This morning,while I was viewing the web pages on the internet,a topic entitled "Do you like smiling?" jumped into my sight.There is one classic motto said "One mere smile makes you ten years younger."Should I be happy while no funny thing happened? In contray,I should be happy while there is not any unhappy thing happpened.Smile is an ingredient to a happy life.It is a component of our daily life.If you want to have a cheerful personality,there is a simple and useful method is to wear a hearty smile on your face from time to time.Although I am still a student without a proper job and high salary ,I have the most valuable asset in the world ,a beloved husband and a holistic family overflow with love,I have a bright future,a specific goals of my life.Above all,I have a grateful heart.Happiness has nothing to do with money or any other materials,what works to our happiness is our heart ,a grateful heart as well as our attitude to our common life.Modern people suffer a lot from the heavy pressure of the work,study and the stiff competition,sometimes,you smile to life,the life might not smile back in return.It doesn't matter,when you encounter the frustration or difficulties in the daily common life,just cheer up and smile to the mirror,then you will have a good mood,everything will be changed satisfactory,I believe.
