right is a one way road.

Nice can be good or worse. it also can be hurt but at the same time make you happy.
nice is a word that stabilizing 'not perfect' or 'not goin well but its ok'.
in other hands,right is compilation of both good and worse,and define happiness and hurt on the same word.
while nice let you take the half of neither good or worse,yet happy or hurt.
right wont let you bother,it comes in one package.you take it or leave it.

JUST TAKE IT OR LEAVE IT.NO TURNING BACK.
