I have a friend who likes to turn to heart-warming and inspiring quotations when she finds the going difficult or when she's experiencing 'a bad day'.
Her favourite author is Victor Hugo, the French poet and novelist who wrote the classic 'Les Miserables.'
She finds these words particularly uplifting....
Have courage for the great sorrows of life and patience for the small ones.
Then, when you have laboriously accomplished your daily task,
go to sleep in peace.
For God is always awake.
