Is being a teacher better than working at a McD or as a Janitor?

If you do it right, it is by no means blah! Also, think about it. If you work at McDonald's, your contribution to the world is that you fill people up in an unhealthy way every day. If you are a janitor, you clean things up, only to have them become just as dirty again the next day. But if you are a teacher, you can change people's lives permanently. That alone makes it worthwhile.
