The reason I bring this up is that there's a rumor out there that humans, on a daily basis, only have access to 10% of their brainpower. The remaining power is "untapped potential" which, if we could access it would give us magical powers. Of course, this isn't true. A quick trip to the internet busts this as a myth...but still it's an interesting concept. What could you actually do if you put all your physical, mental and emotional efforts towards it?
For example, since school is out for the summer, I have the great privilege of putting all my efforts towards my graduate school work. Yes, it's fascinating, I know. Today, I woke up, walked the dogs, and then sat down and wrote a 15 page paper. Done. Now, normally, this would take me at least a week, maybe longer as my attention would be constantly taken by other distractions, but today I tuned them out and got the work finished. It really makes me wonder what students could accomplish in a single high school course if they weren't distracted by 1) Life 2) Each other 3) All the other courses they have to take 4) Not being in the proper physical space for them to work. I'd bet a 15 page paper wouldn't seem so bad to them either.
Sadly, we'll never know. Our students must be experts in all subjects to get all A's, and they must be competent in all subjects to pass and graduate. This leaves little time for 100% effort in anything.
