Time is The Longest Distance Between Two Places

When you waiting for something good to happen, there are times when time goes by fast and times when it goes by slowly.  In this case, and contrary to physics, time is a not a constant.  Nor are you.  I suppose it's all in your personality and attitude.  Sometimes, when you are really busy, feeling well, and are happy, time seems to fly by.  Sometimes, when you are tired and frustrated, time goes by incredibly slowly.  Maybe, in the end, these differences even out and time is really moving at constant rate.  Hmmm ... I wonder.
