I like some of these quotations -  they are worth repeating:

A poor life this if, full of care,
We have no time to stand and stare.

William Henry Davies,  1871 - 1940

Life is easier to take than you'd think;
all that is necessary is to accept the impossible,
do without the indispensable and bear the intolerable.

Kathleen Norris, American author (1880 - 1960)

No man is an island, entire of itself .......
Any man's death diminishes me, because I'm involved in mankind, and therefore never send to know for whom the bell tolls, it tolls for thee.  

John Donne (1572 - 1631)


We have enough religion to make us hate, but not enough to make us love one another.

Jonathan Swift, English writer (1667 - 1745)

Man does not cease to play because he gets too old,
Man grows old because he ceases to play.
George Bernard Shaw.
