I sometimes have a hard time reconciling between effort and output.
On one hand, I have studied with an hour commute AND sleeping problems.
Then after all the stress and studying, I see average results. >:(
But when I also see algebra mistakes like the one I mentioned, then I think again.
Right now I am reconciling by saying that our greatness is measured by the effort we put, and if we get stupid results then many a time it is due to a bad upbringing.
I love to learn… but I hate school. I am sure my students feel the same.
