to be fair, there are times when our attention is at our best,
and then we rest for a while before going back...as for airport,
there will be quiet times, where you can "charge", and slower when
there are more people.
but fast food place, can?? not only people, the music, and even the
food smell..
aren't them big distractions?
furthermore, you are occupying places that are meant for
customers.
(well, one coke doesn't entitles you to a place for four)...
don't you feel bad when you know it is quite crowded and yet you
are there pretending to absorb that important concepts??
To be objective, I do believe there are some who are discipline to
accomplish their study goals, but frankly, far and few if you ask
me.
