What’s the significance of HAPPY?

One day, the psychologist came to an outstanding high school for a speech. In his speech, he asked the hundreds of excellence of students, “What did you so strive for studying?”
“In order to entering the great university,”
“What’s the purpose for?”
“HAPPY…!...?” @#$*&%#^%_ Well, what’s the significance of happy?
Follow the era’s transition every generation has different consciousness, living the nowadays people have the identical comment concerning the rich, successful, and achievement can make them happy.
However, when people’s lives become more perfectly, and what about their family, personal relationship, faith, and soul?

I think the human living in nowadays; their values of life are totally transformed inflexible and dangerous. It becomes more attacking, more extreme, and more selfish; instead of few human have introspection and thinking. Even the society, teacher, and some of leaders taught them, “it is good for greedy!” therefore, what is dying for? Well, I think the answer will be relieved and sense of security can gain the real happiness, or to LOVE people and to pay for someone.
