One moment of patience may ward off great disaster. One moment of impatience may ruin a whole life. -Anon

For everything there is a season,
And a time for every matter under heaven:
A time to be born, and a time to die;
A time to plant, and a time to pluck up what is planted;
A time to kill, and a time to heal;
A time to break down, and a time to build up;
A time to weep, and a time to laugh;
A time to mourn, and a time to dance;
A time to throw away stones, and a time to gather stones together;
A time to embrace, And a time to refrain from embracing;
A time to seek, and a time to lose;
A time to keep, and a time to throw away;
A time to tear, and a time to sew;
A time to keep silence, and a time to speak;
A time to love, and a time to hate,
A time for war, and a time for peace.
 
Ecclesiastes 3:1-8
 
 
You can learn many things from children. How much patience you have, for instance. -Franklin P. Jones: 

Patience and perseverance have a magical effect before which difficulties disappear and obstacles vanish. -John Quincy Adams:
 
Patience is the companion of wisdom."  --St. Augustine

And remember -the extra mile isn't half as long as all those other miles.
