LOVE is the word which can make any sentence beautiful, and HAPPYNESS is the word which can make anyones life beautiful.
LOVE gives HAPPYNESS.
If we love plants by nourishing them with water everyday they will be happy as a result they love you by giving us fruits and flowers.
If we love poor and needy by helping them, their happyness smile on their face gives us happyness. If we love what we are doing the results of our doings gives us happyness. If we love the world by keeping it clean and green our way of life becomes good that gives us happyness.If we love our friends and family that gives us happyness. So LOVE and HAPPYNESS are sharable they should not be kept ourselves.
And there should be no Y in happIness because happiness starts with I(us) not with Y(variable:others). If we are happy, world will be happy and if we love our world, the world loves us.
