<human>: Do grades really completely determine your future?

Is the future, mostly the near future involving college, earning degrees, and getting a job that you don't hate as monolithic as people make it to be?

I am passionate about Physics, Technology, Music, and Languages but I will likely not get a job in Music because to this day I can only play the recorder and I can't read sheet music. I probably won't get a job in Physics and Technology because I suck at Math (which I can fix, I just need to work harder). I could get a job in Languages or Interpretation but that doesn't get my blood pumping as much as the other two.

Can you provide a brief overview of the text?
