The longer we dwell on our misfortunes, the greater is their power to harm us.

Health is the soul that animates all the enjoyments of life, which fade and are tasteless without it.

With the fearful strain that is on me night and day, if I did not laugh I should die.

I know that I am intelligent, because I know that I know nothing.

If you want a love message to be heard, it has got to be sent out. To keep a lamp burning, we have to keep putting oil in it.
