Study For What?

We study is just want to get the certificate, so that we can get a better jod for a high salary....Or We Study is because we want to learn more? to have more knowledge?Nowadays many people study is just want to get the cert, many of them are not really interested in study, So some of them will not get a good result but they still can get the cert...Do you think what we study now are really gonna be useful for us in future? Are we going to apply what we have learned in future? Why We Need To Study So Much? LoL...
