teaching time (teaching)

It is one of those times when I feel like I cannot do all I am
required to do as a teacher. The overwhelming paperwork is getting
much of my attention at the moment. But, the worst part is that the
end of the year is coming and I don't know if I have done enough for
my students. So many moments were wasted, opportunities missed, and
confusion prevailed. I only have 40 days left with them...how much
more will I be able to do?
