About the happiness When i go to the college ,i learned the happiness can be defined by how much the effectiveness get to your exception in economics .And it can be show with the formula-happiness=effectiveness/exception.It means that the same things which effectiveness alike generally ,exceptions more,happiness will be less.So i thought content is happiness. Later, after the movie<The pursuit of happiness>,i consider happiness includes more except the clothes,bread,school work and content.Just like the saying goes"You got a dream ,you gotta protect it .If you want something,you get it." It means not only you should have a dream ,but also to achieve it as far as possible. The way that leat to succeed has many setback impeding your steps certainly .What you can do is hold on it,believe in perseverance means victory ,the process of chasing dream is the happiness.
