“Do what you feel in your heart to be right – for you’ll be criticized anyway.” ~ Eleanor Roosevelt
"The day is ending and our life is one day shorter.
Let us look carefully at what we have done.
Let us live deeply each moment in freedom,
so the time doesn’t slip away meaninglessly."
~Thich Nhat Hanh
"Beauty is whatever gives joy." ~ Edna St. Vincent Millay
