Famous quotes containing the word heart:
“Time, thou anticipatst my dread exploits.
The flighty purpose never is oertook
Unless the deed go with it. From this moment
The very firstlings of my heart shall be
The firstlings of my hand. And even now,
To crown my thoughts with acts, be it thought and done:”
—William Shakespeare (15641616)
“Farewell, my Youth! for now we needs must part,
For here the paths divide;
Here hand from hand must sever, heart from heart,
Divergence deep and wide.”
—Rosamund Marriott Watson (18631911)
“We shall make mistakes, but they must never be mistakes which result from faintness of heart or abandonment of moral principles. I remember that my old school master Dr. Peabody said in days that seemed to us then to be secure and untroubled, he said things in life will not always run smoothly, sometimes we will be rising toward the heights and all will seem to reverse itself and start downward. The great thing to remember is that the trend of civilization itself is forever upward.”
—Franklin D. Roosevelt (18821945)
