As green symbolizes fertility,growth and life. A human life must experience green,if not such life possibly is in extinction. People seek greener pastures in aspiration to add values to thier lives,whereas changing someones environment doesnot only guarrante happiness if all other desireable factors were not present in the new environment.
Attitude is the major determinant factor that can make someone successful in life. You can have everything new in life such as new hair cut,car,house,clothes,friend,meal,job,pet e.t.c But if your attitude doesnot change,there is no difference to be noticed because attitude is like flat tyre which can slow down the movement of any vehicle.
