Don't worry? Be Happy?

Where does life stop being living, and become the monitinous drudgery?

When does my life get good again? Right now I have the majority of my time worrying about classes and shit. And very little worrying about the good things in my life. What is wrong with just being happy? Why do I need all the shit? Why do I need college, and jobs, and every piece of junk in the world?

Why can't I just... be happy?
