As artists our time is spent primarily with ourselves.  The hours fly by unencumbered.  Creativity knows not the limits of time and as we become engaged in our work, time, for us, seems to stand still.  Others may look upon our solitary seclusion as selfish and to some extent that applies.  However, that solitude is the well spring for creative endeavors.  There is one caveat however.  Gathering with other artists grows us as we exchange experiences.  Take time out at least once a month to be with other artists.
