what I didn't want to learn but i did?

in this class i learned that some people teach common sense, which is really weird because its like learning stuff you know already again. so far this class sucks, the work is boring and stupid its basically your own opinion. I also learned that doctors get paid alot.... I think that doctors is a giant health risk thats why they get paid so mush because you have to do with blood which carries diseases and its easy to catch because your around it all the time I would be a doctor but I get nervous so I won't now how I would do it Would be cool though get paid alot and make friends and wear scrubs
