Carry On

Sometimes I am so tired I don't know what to do with myself.  In class today I was doing my best to listen attentively but must admit that I dozed off a couple of times.  Not sure if I bobbed my head or not, there was no violent awakening jerk or anything of the sort.  I was very subtle when I woke up, slow moving like unto a sloth.  I did my best not to draw attention to myself.  Well, what does one do when they are exhausted but have a number of responsibilities on their shoulders that time doesn't stop for?  I do my best to carry on. It isn't always easy and sometimes I just need a power nap to carry me through.
